+Fireflies v2.07
+===============
+by Matt Perry <[email protected]>
+
+TO COMPILE/INSTALL:
+type:
+    ./configure [--with-bindir=PATH_TO_YOUR_XSCREENSAVER_HACK_DIR]
+	[--with-confdir=PATH_TO_YOUR_XSCREENSAVER_CONFIG_DIR]
+    make
+    make install
+    ./add-xscreensaver PATH_TO_YOUR_XSCREENSAVER_FILE
+
+NOTES for Linux:
+The default installation directory for fireflies is /usr/lib/xscreensaver.
+The default installation directory for fireflies.xml (the xscreensaver
+config file) is /usr/share/xscreensaver/config.  If yours differ from this
+(as it almost certainly will), you need to run ./configure with the
+--with-bindir and/or --with-confdir options to tell it where to install.
+Alternatively, you could just copy the binary and .xml file to the right
+places yourself.
+To use with xscreensaver, you must add the fireflies entry to your
+~/.xscreensaver file.  ./add-xscreensaver does this for you.  Just run
+    ./add-xscreensaver PATH
+where PATH would usually look like ~/.xscreensaver
+
+TO INSTALL (windows):
+If you want the standalone program (for which you need SDL, see below),
+run "./configure --disable-screensaver".  Copy the 'fireflies.exe' program
+to wherever you want to put it.
+If you want the screensaver, configure and compile as usual (screensaver is
+the default).  By default, "make install" will put fireflies.scr in your
+C:\Windows\ directory, which is where it should be.  Leave it there.  You
+can set it up by changing your Display Properties (right click on the
+desktop), and selecting 'fireflies' from the pulldown menu.  Clicking on
+Settings will open up a configuration window.
+
+NOTES:
+This program uses the libgfx graphics library (included with this package)
+for basic vertex and rotation processing, available from
+http://graphics.cs.uiuc.edu/~garland/software/libgfx.html
+
+Requirements:
+    openGL and GLU (available from www.opengl.org)
+
+Optional:
+    SDL (available from www.libsdl.org)
+	- SDL will allow you to run fireflies as a standalone program and
+	  let you do cool things like pause and move the camera, and
+	  trigger major modes by pressing number keys [0-6]  If you don't
+	  have it, fireflies will only be able to draw to the root window
+          (ie, as a screensaver), and will not respond to input.
+    Linux only: glX for xscreensaver support

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+version 2.07:
+	* fix for dual-headed display bug.  Thanks to an anonymous tip for finding
+	this.
+	* new FC4 spec courtesy of Simon Roberts.
+
+version 2.06:
+    * fixed a bug with mode probalities where every part was off by 1.
+    * added a French resource.rc (resource.rc.french).  Rename it if you're
+    French.  Thanks to Stephane Sudre for this and the Mac OS X port.
+
+version 2.05:
+    * put back autoconf GLX detection into configure.ac (don't know how that
+    disappeared).
+    * code cleanup: separated GLCanvas into CanvasGLX and CanvasSDL for the
+    different backends.
+
+version 2.04:
+    * whoops: I broke it pretty good.  This release fixes it
+    * small addition: fixed jaggy lines caused when fireflies runs on a slow
+    or busy machine.
+
+version 2.03:
+    * added a default "do nothing" mode with hardcoded probability 10 (so you
+    can make modes less frequent)
+    * added small shell script to add a fireflies entry to your xscreensaver
+    config file.
+    * new package support: Redhat
+    * new package support: Debian (much thanks to Serge Koenigsmann
+    <[email protected]>)
+    * MesaGL support
+
+version 2.02:
+    * fixed xscreensaver support which 2.01 broke
+
+version 2.01:
+    * changed how number of flies and baits work: you now specify a minimum
+    and maximum for each, so that things don't get out of control when
+    adding/killing baits and flies.
+    * -fast_forward option
+    * -fps (frames per second) option
+    * new Faded swarm mode: colors get lighter
+    * added short delays between frames so as not to waste ALL your CPU
+    * some cool new "features" in the SDL standalone program
+    * fixed mode probabilities: made fly birth/kill and swarm merge/split
+    equally likely, so you don't end up with a million flies in 1 swarm after
+    a few hours.
+    * uses autoconf to automatically determine what system you're compiling on,
+    and whether you have SDL, glX, etc
+    * option parsing: uses argp instead of getopt (not that you will notice,
+    it just makes me feel better about myself)
+    * put mode functions in their own file
+
+version 2.0: Fri Feb 21, 2003
+    * new motion algorithm: the fireflies chase after baits that fly
+    around, and freely switch who they're chasing
+    * modes: swarms go through mode changes, such as speeding up, stopping
+    for a breather, and going psychadelic. The overall scene also undergoes
+    mode changes, such as the wind picking up, creation/deletion of new
+    flies/baits, and an... interesting.. matrix mode
+    * new diamond particle shape
+    * sporting a nifty (read: ugly) xscreensaver configuration interface
+    file (Linux only)
+
+version 1.02: Thu Feb 13, 2003
+    * ported to windows (using MinGW)
+    * made it a windows screensaver! even made a config box!
+    * added a -fullscreen option
+    * fixed blending
+
+version 1.01: Sun Feb 10, 2003
+    * added wind to blow the tails around
+    * made it compatible with xscreensaver!
+    * removed dependence on GLUT (incidentally, making it slightly faster)

+-- MODES:
+New to 2.0 are modes.  There are two types, per-swarm modes, and major

+switch to the same mode), while major modes affect the whole scene.  They
+are activated with a certain probability, which is entirely relative.  For
+example, if mode A has probability=1, and mode B has probability=5, that
+means mode B is 5 times as likely to occur as mode A.  The mode numbers,
+names, and descriptions are as follows:
+
+Per-Swarm modes:
+Normal mode (0) - normal swarm flight
+Stop mode (1) - the bait comes to a halt, and the flies circle in around
+	it.
+Loop mode (2) - the bait travels in a loop, and the flies chase it.
+Psychadelic mode (3) - color cycling speed for this swarm is increased, and
+	the tails look like rainbows.
+Glow mode (4) - the tails increase by glow_factor (an option).
+Hyperspeed mode (5) - the bait and flies get hyper, and increase speed and
+	acceleration.
+Faded mode (6) - the colors fade
+
+Major Modes:
+All-Swarm mode (0) - activate a per-swarm mode for all swarms.
+FlyKill mode (1) - kill a bunch of fireflies.
+FlyBirth mode (2) - create a bunch of fireflies.
+Windy mode (3) - wind speed increases.
+Matrix mode (4) - Matrix-style pause and rotate.
+Swarmsplit mode (5) - a random swarm is split in 2.
+Swarmmerge mode (6) - 2 random swarms are merged.
+
+-- SDL standalone program:
+If you have SDL, and you compiled fireflies with SDL support as a
+standalone program (as opposed to a screensaver), you can enjoy a few neat
+features (mostly there so I could test things, but what the hell, they're
+fun for all).
+
+Mouse input:
+    * Left-click and drag to move the camera left/right/up/down.
+    * Right-click and drag up/down to zoom the camera in/out.
+    * Hold control and Left-click and drag to rotate the camera about the
+      origin.
+
+Keyboard input:
+    * q = quit
+    * p = pause the screensaver (you can move the camera, but nothing else
+	  happens)
+    * t = display elapsed time in seconds to the console window (this won't
+	  work in windows if you don't have a console window open)
+    * up arrow = fast forward 2x
+    * down arrow = fast forward 1/2x
+    * right arrow = fast forward +1x
+    * left arrow = fast forward -1x
+    * 0-6 = activate major mode corresponding to that digit
+    * shift + 0-6 = activate swarm mode corresponding to that digit
+    * control + 0-6 = stop swarm mode corresponding to that digit

+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+-Defaults for the options are specified in brackets.
+-
+-Configuration:
+-  -h, --help              display this help and exit
+-      --help=short        display options specific to this package
+-      --help=recursive    display the short help of all the included packages
+-  -V, --version           display version information and exit
+-  -q, --quiet, --silent   do not print \`checking...' messages
+-      --cache-file=FILE   cache test results in FILE [disabled]
+-  -C, --config-cache      alias for \`--cache-file=config.cache'
+-  -n, --no-create         do not create output files
+-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+in Version 1.1
+--------------
+
+    o Got rid of the n-vector and n*n-matrix code as it was quite broken.
+
+    o All MxGUI menu commands are visible to external code now.
+
+    o Got rid of the command-line compilation stuff for VC.
+
+    o Moved all the Windows-specific headers -- which have never moved
+      beyond experimental -- into a Windows specific <gfx/win/...> location.
+
+    o Placed all libgfx code in the 'gfx' namespace.  To improve
+      compatibility with old code, the <gfx/gfx.h> header will
+      automatically import this namespace into the default global one.
+      This behavior can be turned off by defining the GFX_NAMESPACE
+      preprocessor symbol.
+
+    o The scripting framework now allows for encapsulation of one syntax
+      inside another.  However, this is experimental, and is likely to
+      change considerably in a future release.
+
+    o Extended the script interface to support void parsers that throw
+      exceptions on errors rather than passing return codes.  In future,
+      this will become the default way of writing parser functions.
+
+    o The script_do_xxx() functions formerly defined in <gfx/script.h>
+      have been removed.  They were long ago superseded by the
+      CmdEnv::do_xxx() methods.
+
+    o Fixed the unitize() method for quaternions, which did not in fact
+      result in a unit quaternion. 
+
+    o Added a small collection of useful color manipulation routines in
+      <gfx/color.h>.
+
+    o Added an ortho_camera_lookat() function to complement the
+      longstanding camera_lookat() perspective function.
+
+in Version 1.0.3
+----------------
+
+    o When compiling with GCC, warnings are turned on by default.  To
+      compile without warnings, you must use --disable-warnings when
+      running the 'configure' script.
+
+    o The tests used by the 'configure' script to detect OpenGL headers
+      were a bit broken.  These tests are now much more reliable.
+
+    o The quaternion SLERPing code in previous revisions was incorrect
+      due to a typo in the code.  This problem has been fixed.
+
+    o The file parser provided by <gfx/script.h> now supports the use of
+      libgzstream.  When using the library, the scripting code will
+      automatically decompress files ending with {.gz, .z, .Z} suffixes.
+      You must use the --enable-gzstream option when running ./configure.
+
+    o New experimental build files for use with Apple's XCode
+      development environment are available in the 'xcode' directory.
+
+    o Added functions to <gfx/geom3d.h> for computing the volume
+      of tetrahedra.
+
+    o The MIN/MAX macros were broken under Cygwin.
+
+    o Fixed up a few miscellaneous compiler warnings.
+
+    o Added an experimental MxBinder class to <gfx/gui.h>.  This makes
+      it fairly painless to bind MxGUI member functions to FLTK callbacks.  
+
+    o Moved management of libgfx source code from CVS to Subversion.
+
+
+in Version 1.0.2
+----------------
+
+    o The MxGUI::snapshot_to_file() method now takes an optional
+      filename argument.  When provided, the code will simply write a
+      snapshot to this file, rather than presenting the user with a file
+      selector.
+
+    o The MxGUI::snapshot_to_file() method will now save the alpha
+      channel of the window, assuming the file format supports that.
+      (Currently, only PNG and TIFF support alpha channels.)
+
+    o MxGUI OpenGL windows allocate alpha channels (when available).
+
+    o New vector/matrix modules: 
+
+	- <gfx/symmat4.h>   Symmetric 4x4 matrices; after <gfx/symmat3.h>
+	- <gfx/vecn.h>      Preliminary support for n-D vectors
+	- <gfx/matn.h>      Preliminary support for nxn matrices
+	- <gfx/symmatn.h>   Preliminary support for nxn symmetric matrices
+
+    o Project files for Apple's ProjectBuilder (OS X) are located in the
+      macos subdirectory.
+
+    o Added checks in the autoconf script for <ext/hash_map> and
+      <ext/hash_set>, which is where GCC3 chooses to place these
+      non-standard STL components.
+
+    o The scripting framework now supports a CmdEnv::ignore_command()
+      method that lets client code specify command names that should be
+      ignored.  This is also available from the input file itself by
+      using the 'ignore' command.
+
+    o The Baseball-derived classes now have read()/write() methods for
+      exchanging view information in a textual form.
+
+
+in Version 1.0.1
+----------------
+
+    o The library should now compile correctly under Visual Studio .NET
+      (a.k.a Visual C++ 7).
+
+    o The array<> and varray<> templates in <gfx/array.h> have been
+      removed.  Their original purpose was to support legacy code
+      written in prior to the widespread adoption of STL.  The array2<>
+      and array3<> templates remain, but they are now subclasses of
+      std::vector<>.
+
+    o Many of the functions in <gfx/geom3d.h> were re-written to by
+      templatized by vector class rather than by element type.  Thus,
+      they may now be used with any suitable vector type, not just the
+      TVec3<> template defined in <gfx/vec3.h>.
+
+    o The CmdLine::collect_as_xxx() methods used by the file format
+      scripting interface now accept an optional 'offset' argument.
+      This parameter controls at which token the methods start reading.
+      Their previous behavior was to always begin reading at the first
+      token on the command line.
+
+    o The script_do_xxx() functions have been replaced with
+      CmdEnv::do_xxx() methods.  The old global functions remain in
+      place for compatibility, but the new CmdEnv methods should be used
+      in preference to them.
+
+    o The autoconf process now sets up a symbolic FLTKCONFIG program
+      name.  This is primarily of interest under MacOS X, where the
+      fltk-config program is used to finalize the build of a GUI
+      application so that it will launch correctly from the Finder.
+      The Makefile in the 'test' directory demonstrates the correct use
+      of this program as a post-build step.
+
+    o Bug fixes:
+
+	- The Raster destructor is now correctly declared as virtual.
+
+	- Certain type declarations have been made more rigorously
+	  correct for proper compilation under GCC 3.
+
+    o A geom4d package has been added that provides functionality
+      analogous to the geom3d package.
+
+    o A couple of new experimental packages have been added for building
+      Win32 interfaces with MFC: mfc, wintools, gui-mfc.  They are
+      unfinished, undocumented, and may be unstable.  Most users of this
+      library will want to avoid them.
+
+
+in Version 1.0
+----------------
+
+    o The documentation is now (mostly) complete and (mostly)
+      synchronized with the actual code.
+
+    o Trackball & Arcball now share a common Baseball base class.
+
+    o Extensions to the autoconf script to allow for:
+
+	- Automatic configuration under Mac OS X
+
+	- Selection of whether to compile with Cygwin libraries or not
+
+	- Handle differences between FLTK 1.0.x and 1.1.x in the way
+	  that OpenGL code is handled
+
+    o Some minor changes to make the library compile under Mac OS X.
+
+    o Bug fixes:
+
+	- ByteRaster copy constructer faulted due to incorrect size
+	  computation for memcpy().
+
+in Version 0.9.3
+----------------
+
+    o Even more significant changes in the file format scripting package.  The
+      old approach was getting increasingly unmanageable, and the reliance on
+      magic global constructors for handler registration was proving to be
+      problematic.
+
+    o Added descriptive interface to vector/matrix types to make
+      templates easier to write.
+
+    o Vector templates now handle assignment between vectors of
+      different types (e.g., Vec3 and Vec3f) much more cleanly.
+
+    o New packages to efficiently support symmetric matrix types
+    (e.g., <gfx/symmat3.h>).
+
+    o Added is_inside_bbox() and clamp_to_bbox() to geom3d package.
+
+    o More complete documentation.
+
+    o Bug fixes in various packages:
+    
+	- fixed autoconf script to correctly detect headers
+
+	- Raster class now uses delete[] to match its use of new[].
+
+	- Scalar multiplication of vectors under VC++ must now use
+	  constants of the same type as the vector elements.  This
+	  prevents a tricky bug related to the VC++ template
+	  instantiation.
+
+
+in Version 0.9.2

+    o Significant changes to the file format scripting package.  All previous
+      global functions are still available for backwards compatibility, but
+      you may need to change the definitions of your command handlers.
+
+    o The interface of the <geom3d> package has changed considerably
+
+	- Changed the triangle_* functions to be inlined templated functions.
+	  Before they only worked with Vec3's.  Now, they'll work with any
+	  TVec3<T> type.
+
+	- Added a templated compute_bbox() function.
+    
+    o Camera and object control has changed a bit
+
+	- The camera_lookat() function in the <gltools> package was putting
+	  both the perspective and lookAt transformations on the Projection
+	  stack.  It now correctly puts the perspective on the Projection
+	  stack and the lookAt transformation on the ModelView stack.
+
+	- The Arcball and Trackball manipulators now apply all transformations
+	  to the object, rather than applying rotation to the object and
+	  translation to the camera.
+    
+    o Added eigenvalue/eigenvector functions for all matrix types.
+
+	- Because of licensing restrictions, only the 2x2 implementation is
+	  actually present, although prototypes exist for all dimensions.
+
+    o Added a restricted STL-like interface to <array> package.
+    
+    o Bug fixes in various packages
+
+	- The 2x2 matrix inversion method was incorrect.
+
+	- read_tiff_image() always returned a 3-channel image.  It will now
+	  return an image with the same number of channels as in the file
+	  read.
+
+
+in Version 0.9.1
+---------------
+
+    o Added a new quaternion package <gfx/quat.h>. [currently undocumented]
+
+    o Added Trackball & Arcball interactive rotation control packages.  This
+      makes it much easier to write applications where the user interactively
+      spins a model in the window. [currently undocumented]
+
+    o Bug fixes in various packages.
+
+	- Vec3, Vec4 operators for Visual C++ were broken.
+	- Fixed improper deallocation of array2<> and array3<> objects.
+	- camera_lookat() incorrectly computed camera location.
+
+    o Applications built on the MxGUI framework can now receive key
+      press events in the OpenGL canvas area by overriding the key_press()
+      method.
+
+
+in Version 0.9
+-----------
+
+    This was the initial preliminary release for Fall 2000.

+			  libgfx: A Graphics Library
+				Version 1.1.0
+
+		      Michael Garland <[email protected]>
+          http://graphics.cs.uiuc.edu/~garland/software/libgfx.html
+
+		  Copyright (C) 1999-2005 Michael Garland.
+
+------------------------------------------------------------------------
+
+OVERVIEW
+--------
+
+The purpose of this library is to simplify the creation of computer graphics
+software.  Specifically, it is targeted towards cross-platform development
+using the OpenGL rendering API and the FLTK interface toolkit.  It attempts to
+provide facilities which are useful in the majority of graphics programs.  It
+is derived from the MixKit library I wrote for doing polygonal surface
+simplification (see http://graphics.cs.uiuc.edu/~garland/software/qslim.html).
+
+Instructions on building and using the library can be found in the 'doc'
+subdirectory.
+
+
+
+CURRENT STATUS
+--------------
+
+After having gone through multiple pre-release versions, the first
+official version (1.0) was released in March 2002.  The changes made in
+successive 1.0.x series releases were meant primarily to fix bugs and
+add new functionality.  The current 1.1.x series of releases makes
+certain incompatible changes to the code, such as moving headers and
+removing support for out-dated mechanisms.
+
+While the license for this library does not require it, I'd like to
+encourage you to contribute bug reports, patches, and whatever
+improvements you might come up with to this library.  In that way,
+others can benefit from your efforts, and you can benefit from the
+efforts of others.

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

+			  [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',

+<title>libgfx: Building the Library</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">

+</head>
+
+<body>
+
+<h2>Building the Library</h2>
+
+<p><tt>libgfx</tt> is a C++ library which is meant to be fairly easy
+to compile on a wide range of systems.  It was developed under Windows
+NT 4.0, Windows 2000, and RedHat Linux 6.
+
+<p>This library does make use of the ANSI C++ Standard Library.  For
+instance, it uses the new <tt>&lt;iostream&gt;</tt> rather than the
+old <tt>&lt;iostream.h&gt;</tt> package.  And it does make some
+minimal use of the Standard Template Library (STL).  Therefore, it may
+not work on older C++ compilers.  It is known to work on Microsoft
+Visual C++ version 5.0 and above and GNU GCC version 2.9 and above.
+
+<p><strong>Required</strong> external libraries:
+<ul>
+<li>The <a href="http://www.fltk.org">FLTK</a> graphical interface toolkit.
+<li>An <a href="http://www.opengl.org">OpenGL</a> library
+or the <a href="http://www.mesa3d.org">Mesa</a> library.
+</ul>
+
+
+<p><strong>Optional</strong> external libraries:
+<ul>
+<li>The <a href="http://www.libtiff.org">libtiff</a> library for TIFF image
+file support
+
+<li>The JPEG support library from the
+<a href="http://www.ijg.org">Independent JPEG Group</a>
+
+<li>The <a href="http://www.libpng.org/pub/png/">libpng</a> library
+for PNG image file support.
+
+</ul>
+
+
+<h3>For Windows Systems</h3>
+
+
+
+
+<h4>Visual C++</h4>
+
+<p>A Visual C++ 6.0 workspace and accompanying project files are
+provided in the <tt>vc6</tt> directory.
+An older VC++ 5.0 workspace is available in the <tt>vc5</tt> directory.
+However, this is no longer in regular use and may be out of date.
+
+<h5>Manual Build</h5>
+
+<p>The library can also be built manually using the <tt>nmake</tt>
+command line tool.  A <tt>configure.bat</tt> batch file is provided
+which will set up the necessary configuration files.
+
+<p>To build the library manually, use the following process:
+<ol>
+<li><tt>configure.bat</tt>
+<li><tt>cd src</tt>
+<li><tt>nmake /f Makefile.vc</tt>
+</ol>
+
+
+<h4>Cygwin</h4>
+
+<p>The <tt>libgfx</tt> library will build properly under Windows with
+ the <a href="http://sourceware.cygnus.com/cygwin/">Cygwin</a>
+ toolset.  Simply follow the directions for <a href="#unix">Unix
+ systems</a>.
+
+
+
+
+<h3><a name="unix">For Unix Systems</a></h3>
+
+<p>The Unix build process relies on the GNU
+<a href="http://www.gnu.org/software/autoconf/autoconf.html">Autoconf</a>
+system to properly configure the software.
+
+<p>Once the required libraries are installed, you should be able to
+build the library using the following process:
+<ol>
+<li><tt>./configure</tt>
+<li><tt>cd src</tt>
+<li><tt>make</tt>
+</ol>
+If the support libraries are installed in a directory outside the default
+search path, you can invoke the <tt>configure</tt> script with the option
+<tt>--with-local[=dir]</tt> which will add "dir" to the search path.  The
+default local directory is <tt>/usr/local</tt>, but you can specify any
+directory of your choice.
+
+<h3><a name="macosx">For Mac OS X Systems</a></h3>
+
+<p>The current version of <tt>libgfx</tt> can be successfully compiled
+under Mac OS X, but it requires a bit of manual intervention.
+
+<p>First, you should install the FLTK library.  To build under Mac OS X,
+you must use version 1.1.0 or later.
+Next, you should follow the instructions for using the Autoconf
+script outlined in the <a href="#unix">directions for Unix systems</a>
+above.
+
+<p>This is sufficient to compile command-line programs.  However, GUI
+programs require a little extra work.  The typical GUI <tt>make</tt> rule looks
+like this:
+<pre>
+    gui-program: gui-program.cxx
+	    $(CXX) -o $@ $^ $(CXXFLAGS) $(LDFLAGS) -lgfx $(GUI_LIBS) -lm
+</pre>
+To work correctly with the Mac OS, you must add an additional step to
+this <tt>make</tt> rule:
+<pre>
+    gui-program: gui-program.cxx
+	    $(CXX) -o $@ $^ $(CXXFLAGS) $(LDFLAGS) -lgfx $(GUI_LIBS) -lm
+	    $(FLTKCONFIG) --post $@
+</pre>
+This uses the <tt>fltk-config</tt> script to add a standard resource
+fork to the compiled application.

+<body>
+
+<h2>Simple GUI Example Program</h2>
+
+<p>This is a very simple program which uses the minimalist <a
+href="gui.html">GUI</a> facility provided by <tt>libgfx</tt>
+to create a window a draw a red square in it.  When first started, it
+presents the user with a window which looks like the one shown below.
+The full source code for this example application can be found in
+the file <tt>tests/t-gui.cxx</tt> in the <tt>libgfx</tt> source
+distribution.
+
+<p>
+<div align=center>
+<img src="gui-redbox.gif">
+</div>
+
+<h3>Setup</h3>
+
+<p>The program begins by including some of the standard
+<tt>libgfx</tt> headers.
+
+<pre>
+#include &lt;gfx/gfx.h&gt;
+#include &lt;gfx/gui.h&gt;
+#include &lt;gfx/gltools.h&gt;
+</pre>
+
+<p>The first step in using the <tt>libgfx</tt> GUI framework is to
+subclass the <tt>MxGUI</tt> class and override whatever handlers you
+want to write code for.  After defining the subclass, you must then
+create a <em>single</em> instance.  In this application, we override
+the handlers involved with drawing and mouse events.
+We also follow the recommended idiom of naming our derived subclass
+<tt>GUI</tt> and its lone instance <tt>gui</tt>.
+
+<pre>
+class GUI : public MxGUI
+{
+public:
+    float angle, opt_theta, center[2];
+    bool dragging;
+
+public:
+    <i>// Drawing-related handler methods</i>
+    virtual void setup_for_drawing();
+    virtual void draw_contents();
+    virtual void update_animation();
+
+    <i>// Mouse-related handler methods</i>
+    virtual bool mouse_down(int *where, int which);
+    virtual bool mouse_up(int *where, int which);
+    virtual bool mouse_drag(int *where, int *last, int which);
+};
+
+GUI gui;
+</pre>
+
+
+<h3>Application Entry Point</h3>
+
+<p><tt>MxGUI</tt> programs always use the <tt>main()</tt> procedure as
+their entry point, even on Windows systems.  This application follows
+the recommended sequence of actions
+<ol>
+<li>Initialize member variables defined by the <tt>GUI</tt> derived class.
+<li>Call <tt>gui.initialize()</tt> to parse the command line and
+create the application.
+<li>Customize the default application by changing labels, adding
+menus, etc.
+<li>And finally, call <tt>gui.run()</tt> to open the application
+window and begin the event loop.
+</ol>
+These four distinct phases are indicated in the program source by
+whitespace-separated blocks.
+
+<pre>
+main(int argc, char **argv)
+{
+    gui.opt_theta = 10.0f;
+    gui.angle = 0.0f;
+    gui.dragging = false;
+    gui.center[0] = gui.center[1] = 0.0f;
+
+    gui.initialize(argc, argv);
+
+    gui.toplevel->label("Simple GUI Example");
+
+    return gui.run();
+}
+</pre>
+
+<h3>Drawing-Related Handler Methods</h3>
+
+<p>Whenever our OpenGL drawing canvas is created, resized, or
+otherwise reconfigured, the <tt>setup_for_drawing()</tt> handler is
+invoked.  This is where you want to set up any graphics state that is
+the same for every frame.
+
+<pre>
+void GUI::setup_for_drawing()
+{
+    glClearColor(0.65f, 0.65f, 0.65f, 0.0f);
+    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
+
+    glMatrixMode(GL_PROJECTION);
+    gluOrtho2D(-1.0, 1.0, -1.0, 1.0);
+}
+</pre>
+
+
+<p>If the contents of the OpenGL canvas need to be redrawn, the
+<tt>draw_contents()</tt> handler is invoked.
+
+<pre>
+void GUI::draw_contents()
+{
+    glClear(GL_COLOR_BUFFER_BIT);
+
+    glMatrixMode(GL_MODELVIEW);
+    glPushMatrix();
+    glLoadIdentity();
+
+    <i>// Draw the black axes</i>
+    glColor3f(0.0, 0.0, 0.0);
+    glBegin(GL_LINES);
+      glVertex2f(-1.0, 0.0);
+      glVertex2f(1.0, 0.0);
+      glVertex2f(0.0, -1.0);
+      glVertex2f(0.0, 1.0);
+    glEnd();
+    
+    glTranslatef(center[0], center[1], 0);
+    glRotatef(angle, 0, 0, 1);
+
+    <i>// Draw the red rectangle</i>
+    glEnable(GL_BLEND);
+    glColor4d(0.8, 0.15, 0.15, 0.85);
+    glBegin(dragging?GL_LINE_LOOP:GL_POLYGON);
+    glBegin(GL_POLYGON);
+      glVertex2f(-0.5, -0.5);
+      glVertex2f(-0.5, 0.5);
+      glVertex2f(0.5, 0.5);
+      glVertex2f(0.5, -0.5);
+    glEnd();
+    glDisable(GL_BLEND);
+
+    glPopMatrix();
+}
+</pre>
+
+<p>The <tt>MxGUI</tt> framework provides a simplistic animation
+mechanism.  Whenever animation is activated --- the user controls this
+via a menu entry --- the event loop will periodically call the
+<tt>update_animation()</tt> handler.
+<pre>
+void GUI::update_animation()
+{
+    angle += opt_theta;
+}
+</pre>
+
+<h3>Mouse-Related Handler Methods</h3>
+
+<p>When the user clicks the left mouse button, we want to re-center
+the square around that position.  We use a call to the
+<tt>unproject_pixel()</tt> <a href="gl.html">utility function</a>
+to map the pixel location into a world-space coordinate.
+
+<pre>
+static bool center_on_click(float *ctr, int *where)
+{
+    double world[3];
+
+    unproject_pixel(where, world);
+    ctr[0] = (float)world[0];
+    ctr[1] = (float)world[1];
+
+    return true;
+}
+</pre>
+
+<p>Given the above code to center the rectangle on a click location,
+it is a simple matter to write our mouse handlers.  Whenever the
+left button is pressed or dragged, we recenter the rectangle.  We also
+maintain the value of <tt>gui.dragging</tt> to indicate whether the
+mouse is being dragged.  If it is, the <tt>draw_contents()</tt>
+handler will draw the rectangle as an outline rather than a filled box.
+
+<pre>
+bool GUI::mouse_down(int *where, int which)
+{
+    if( which==1 )
+    {
+	dragging = true;
+	return center_on_click(center, where);
+    }
+    else return false;
+}
+
+bool GUI::mouse_up(int *where, int which)
+{
+    dragging = false;
+    return (which==1);
+}
+
+bool GUI::mouse_drag(int *where, int *last, int which)
+{
+    if( which==1 )
+	return center_on_click(center, where);
+    else
+	return false;
+}
+</pre>

+
+<h2>Simple Scripted Program</h2>
+
+<p>This program demonstrates some of the basic features provided by the
+<tt>libgfx</tt> <a href="script.html">scripting package</a>.  Given a list of
+file names on the command line, it reads each of them in turn and executes the
+scripting commands contained within them.
+
+<h3>Setup and Initialization</h3>
+
+<p>The program begins by including the headers for the <tt>libgfx</tt> modules
+which it uses:
+<pre>
+#include &lt;gfx/gfx.h&gt;
+#include &lt;gfx/script.h&gt;
+#include &lt;gfx/vec3.h&gt;
+</pre>
+
+<p>The <tt>main()</tt> application entry point performs a very simple task.
+It creates a scripting environment (<tt>class CmdEnv</tt> and registers a set
+of scripting commands.  Once these handlers have been installed, 
+it loops over every file name specified on the command line and executes it as
+a script.
+<pre>
+main(int argc, char *argv[])
+{
+    CmdEnv env;
+
+    env.register_command("add", proc_add);
+    env.register_command("avg", proc_add);
+    env.register_command("echo", proc_echo);
+    env.register_command("vec3", proc_vec3);
+
+    for(int i=1; i&amp;argc; i++)
+	script_do_file(argv[i], env);
+
+    return 0;
+}
+</pre>
+
+<h3>Command Procedures</h3>
+
+<p>Every scripting command is handled by some command procedure.  The
+registration code above binds the actual procedures to the names of their
+scripting commands.  Then, whenever a given command occurs in a script being
+processed, the corresponding handler is invoked.
+
+<p>The first command procedure actually implements two scripting commands:
+<tt>add</tt> and <tt>avg</tt>.  It determines which command has been invoked
+by examining its <tt>name</tt> argument.
+It treats its command line as a whitespace-separated sequence of numbers,
+either adds or averages all of them, and then prints the result.
+<pre>
+int proc_add(const CmdLine &amp;cmd)
+{
+    double sum = 0.0;
+    int count;
+
+    std::vector&lt;double&gt; values;
+    cmd.collect_as_numbers(values);
+    for(count=0; count&lt;values.size(); count++)
+	sum += values[count];
+
+    if( cmd.opname() == "avg" &amp;&amp; count&gt;0 )
+	sum /= (double)count;
+
+    cout &lt;&lt; sum &lt;&lt; endl;
+    return SCRIPT_OK;
+}
+</pre>
+
+<p>This next procedure requires precisely 3 numeric arguments, from which it
+constructs a 3-D vector using the <tt>Vec3</tt> class.  If the number of
+arguments is not 3, it returns a value indicating a syntax error occurred.
+<pre>
+int proc_vec3(const CmdLine &amp;cmd)
+{
+    if( cmd.argcount() != 3 )  return SCRIPT_ERR_SYNTAX;
+
+    Vec3 v;
+    cmd.collect_as_numbers(v, 3);
+
+    cout &lt;&lt; v &lt;&lt; endl;
+    return SCRIPT_OK;
+}
+</pre>
+
+<p>Finally, the <tt>echo</tt> procedure does not interpret its arguments at
+all.  Instead, it simply prints the entire argument line as is.
+<pre>
+int proc_echo(const CmdLine &amp;cmd)
+{
+    cout &lt;&lt; cmd.argline() &lt;&lt; endl;
+    return SCRIPT_OK;
+}
+</pre>
+
+<h3>Sample Execution</h3>
+
+<p>To demonstrate the action of this sample program, here is a particularly
+simple script.
+<pre>
+# This is a test script meant to be fed to t-script.  It is not meant as an
+# exhaustive test, but mainly as a demonstration.
+
+echo The following sum should be 15
+add 1 2 3 4 5
+
+echo
+echo The following average should be 3.5
+avg 3 8 2 1
+
+echo
+echo The following is the vector [1 0 0]
+vec3 1 0 0
+</pre>
+
+<p>When given to the sample program, it produces the following output
+<pre>
+The following sum should be 15
+15
+
+The following average should be 3.5
+3.5
+
+The following is the vector [1 0 0]
+1 0 0
+</pre>

+
+<h2>3-D Geometric Procedures</h2>
+
+<p>Triangles are a very common modeling primitive in many graphics
+applications.  The <tt>libgfx</tt> library provides a package of routines for
+computing various geometric properties of triangles.
+To use this package you must include the standard header file
+<pre>
+    #include &lt;gfx/geom3d.h&gt;
+</pre>
+Note that all of these functions assume that the corners of the triangle are
+listed in <em>counter-clockwise order</em> around the outward pointing normal.
+
+<p>You can compute the (signed) area of a triangle using the following
+function.  Note that the area will be negative if the vertices are listed in
+clockwise order.
+<pre>
+    double triangle_area(const Vec3&amp;, const Vec3&amp;, const Vec3&amp;);
+</pre>
+
+<p>The following functions compute the plane defined by a triangle, and the
+corresponding normal vector.  The standard versions always use unit normal
+vectors while the "raw" versions will use unscaled normals.
+<pre>
+    Vec3 triangle_normal(const Vec3&amp;, const Vec3&amp;, const Vec3&amp;);
+    Vec4 triangle_plane(const Vec3&amp;, const Vec3&amp;, const Vec3&amp;);
+
+    Vec3 triangle_raw_normal(const Vec3&amp;, const Vec3&amp;, const Vec3&amp;);
+    Vec4 triangle_raw_plane(const Vec3&amp;, const Vec3&amp;, const Vec3&amp;);
+</pre>
+
+
+<p>For some meshing applications, it may on occasion be necessary to assess
+the aspect ratio of a triangle.
+<pre>
+    double triangle_compactness(const Vec3&amp;, const Vec3&amp;, const Vec3&amp;);
+</pre>
+This function computes the "compactness" of a triangle.  The returned value
+will be between 0 and 1, with 0 meaning a degenerate (area=0) triangle and 1
+meaning an equilateral triangle.  The formula used, originally suggested by
+Andre Gueziec, is 4*sqrt(3) * Area / (L1 + L2 + L3) where Li is the squared
+length of side <i>i</i> of the triangle.

+<title>libgfx: OpenGL Support</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>OpenGL Support</h2>
+
+<p>
+
+
+<p><strong>Important:</strong>
+The standard way to include the OpenGL headers is to include the
+headers
+
+<pre>
+    #include &lt;GL/gl.h&gt;
+    #include &lt;GL/glu.h&gt;
+</pre>
+
+However, to ensure portability you <em>should not</em> do this; use
+the following inclusion instead:
+
+<pre>
+    #include &lt;gfx/gl.h&gt;
+</pre>
+
+The primary reason for this is that the Microsoft OpenGL headers do
+not work properly unless you have included <tt>&lt;windows.h&gt;</tt>
+first.  This <tt>libgfx</tt> header takes care of the necessary
+<tt>#ifdefs</tt> and keeps your code looking cleaner.
+
+
+<h3>Utility Functions</h3>
+
+
+To gain access to these utility functions, include the header
+
+<pre>
+    #include &lt;gfx/gltools.h&gt;
+</pre>
+
+<p>Given a pixel coordinate in the OpenGL viewport, it is often
+necessary to project this to a 3-D point in the world being displayed.
+You can use the function
+<pre>
+    int unproject_pixel(int *pixel, double *world, double z=0.0);
+</pre>
+to accomplish this.
+
+
+
+<p>To simplify the display of 3-D scenes, the function
+<pre>
+    void camera_lookat(const Vec3& min, const Vec3& max, double aspect);
+</pre>
+will set up a standard viewing geometry for displaying an object
+bounded by the axis-aligned box [<tt>min</tt>, <tt>max</tt>] in a
+window whose aspect ratio is <tt>aspect</tt>.
+The camera will be looking at the center of the box, from a position
+further along the <i>z</i> axis, with a 60&deg; field of view.
+The viewing transform will be multiplied into the current matrix,
+using calls to <tt>gluPerspective()</tt> and <tt>gluLookAt()</tt>.
+
+<p>Errors during OpenGL processing are not reported to the user, they are
+merely flagged in the current OpenGL state.  To check for and report any
+OpenGL errors, you can call the function:
+<pre>
+    void check_opengl_errors(const char *msg=NULL);
+</pre>
+An optional message can be provided which will be prepended to the error
+reported (if any).
+
+<h4>Picking</h4>
+
+<p>Interactive programs frequently need to allow the user to select
+individual components of the scene being displayed by clicking on the
+rendered image.  Given a pixel location in the window, the application
+must determine which entity the user clicked on.
+The standard technique for doing this with OpenGL is with the selection
+buffer.  The <tt>libgfx</tt> library provides some utility functions to make
+using the selection buffer somewhat easier.
+Details on using the selection buffer can be found in the OpenGL Programming
+Guide.
+
+<p>Before drawing your primitives, call the function
+<pre>
+    void begin_opengl_pick(int *ctr, double radius, GLuint *buf, int size);
+</pre>
+with the location of the user's pointer (<tt>ctr</tt>) and
+the <tt>radius</tt> of the region to consider.  You will also need to allocate
+and pass a buffer of object identifiers to hold the candidate objects.
+Having set things up, you can draw your primitives as usual, assigning an
+integer identifier to each using the <tt>glLoadName()</tt> function.
+After all primitives have been drawn, call the function
+<pre>
+    GLuint complete_opengl_pick(GLuint *buffer);
+</pre>
+The returned value will be the identifier of the object clicked on, or
+<tt>opengl_pick_nil</tt> if the user clicked on the background.

+<title>libgfx: Minimalist GUI Framework</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>Minimalist GUI Framework</h2>
+
+<p>All interactive graphics applications need to create some sort of graphical
+user interface.  While many applications may require a fairly sophisticated
+interface, there is a large class of applications which can be built with a
+very simple interface.  The <tt>libgfx</tt> library provides a framework to
+ease the construction of such simple interfaces.
+
+<p>The kind of application interface supported by the GUI framework is
+pictured in the following figure:
+<blockquote>
+<center><img src="gui-layout.gif"></center>
+</blockquote>
+
+The application window consists of three primary components:
+<ol>
+<li>A menu bar, which is managed by the GUI framework,
+<li>An OpenGL canvas window where the application is free to draw its content
+and receive user events such as mouse clicks, and
+<li>A status bar where the application can print text messages.
+</ol>
+
+<p>The <a href="ex-gui.html">code for the application pictured
+above</a> provides a concrete example of using this GUI framework.
+
+<h3>Creating a GUI Application</h3>
+
+<p>To begin building your GUI application, you'll need to include the GUI
+framework header:
+<pre>
+    #include &lt;gfx/gui.h&gt;
+</pre>
+The framework itself is packaged as a C++ class named <tt>MxGUI</tt>.
+You create your application by subclassing it and overriding various virtual
+methods.  You can then create a single instance of this class, which will
+represent your application.
+For consistency, it is recommended that you name
+the derived subclass <tt>GUI</tt> and its instance <tt>gui</tt> as in the
+following:
+<pre>
+    class GUI : public MxGUI
+    {
+    public:
+        <i>// Application variables and methods</i>
+
+    public:
+	<i>// Override virtual methods to handle events</i>
+    };
+
+    GUI gui; <i>// Create application instance</i>
+</pre>
+
+<p>Programs based using this framework always use the <tt>main()</tt>
+procedure as their entry point, <em>even on Windows systems</em>.
+Inside this main procedure, you should perform this general sequence of
+operations:
+<ol>
+<li>Initialize global variables and member variables defined in the
+<tt>GUI</tt> class.
+<li>Call the <tt>gui.initialize()</tt> procedure to parse the command line and
+create the application.
+<li>Customize the default application by changing labels, adding menus, etc.
+<li>Call <tt>gui.run()</tt> to open the application window and begin the event
+loop.
+</ol>
+
+<p>The <tt>MxGUI::initialize</tt> method must be called to initialize the GUI
+framework.
+<pre>
+    virtual void initialize(int argc, char **argv,
+			    Fl_Menu_Item *layout=NULL, int xw=640, int yw=480);
+</pre>
+You should pass to it the <tt>argc</tt> and <tt>argv</tt> command-line
+variables as passed into <tt>main()</tt>.  The framework will take care of
+parsing the command-line and calling the appropriate handlers.
+The optional <tt>layout</tt> argument can be used to specify an initial menu
+structure; the default value of <tt>NULL</tt> directs the framework to use the
+default menu layout.
+The optional <tt>xw</tt> and <tt>yw</tt> arguments specify the desired width
+and height (in pixels) of the OpenGL canvas.
+
+<h4>Command-Line Processing</h4>
+
+<p>
+The <tt>MxGUI</tt> framework uses the FLTK
+<a href="http://www.fltk.org/doc-1.0/functions.html#args"><tt>Fl::args</tt></a>
+facility to parse the command line passed to <tt>MxGUI::initialize()</tt>.
+For each option on the command line, it invokes the following handler:
+<pre>
+    virtual int cmdline_option(int argc, char **argv, int& index);
+</pre>
+The <tt>argc</tt> and <tt>argv</tt> values are the complete array originally
+passed to <tt>initialize()</tt>.  The <tt>index</tt> argument indicates which
+element of <tt>argv</tt> contains the current switch being processed.
+This <tt>index</tt> variable is passed by reference to allow the handler to
+consume additional elements of <tt>argv</tt> by incrementing <tt>index</tt>.
+The handler should return <tt>1</tt> if it handled the switch and <tt>0</tt>
+otherwise.
+
+<p>Once all options have been processed, the initialization code invokes the
+following handler for each file listed on the command line.
+<pre>
+    virtual void cmdline_file(const char *file);
+</pre>
+If no files are specified this handler will be invoked with a <tt>NULL</tt>
+value.
+
+<h4>Drawing</h4>
+
+<p>The <tt>MxGUI</tt> framework uses two virtual methods to control drawing in
+the OpenGL canvas.  The first of these is:
+<pre>
+    virtual void setup_for_drawing();
+</pre>
+This method is called whenever the canvas has been reconfigured.  Primarily,
+this occurs when the canvas has either just been shown on the screen (e.g.,
+after creation) or when it has been resized.
+
+<p>Whenever the canvas needs to be repainted, the framework will invoke the
+handler:
+<pre>
+    virtual void draw_contents();
+</pre>
+You should override this method and place all your drawing code in it.
+
+
+<h4>Handling Mouse Events</h4>
+
+<p>Interactive applications will typically want to receive mouse events taking
+place on the OpenGL canvas.  The framework classifies mouse events into three
+types:
+<ol>
+<li><strong>Button down:</strong>
+	the user has depressed a mouse button
+<li><strong>Button up:</strong>
+	the user has released a previously depressed button
+<li><strong>Drag:</strong>
+	the user is moving the mouse with a button depressed
+</ol>
+When one of these events occur, the corresponding event handler will be
+invoked:
+<pre>
+    virtual bool mouse_down(int *where, int which);
+    virtual bool mouse_up(int *where, int which);
+    virtual bool mouse_drag(int *where, int *last, int which);
+</pre>
+The <tt>where</tt> argument is a 2-D array containing the pixel location in
+the OpenGL canvas at which the mouse was pointing when the event occurred.
+The number of the button involved (either 1, 2, or 3) is passed in the
+<tt>which</tt> argument.
+To simplify drag operations, that event handler is also passed the location of
+the <tt>last</tt> received drag event.
+
+<p>All of these mouse handlers should return <tt>true</tt> if the canvas
+should be redrawn in response to the event just handled.  If the canvas does
+not need to be updated, they should return <tt>false</tt>.
+
+<h4>Handling Key Presses</h4>
+
+<p>Key press events can be received through the virtual function:
+<pre>
+    virtual bool key_press(int key);
+</pre>
+The return value of this function indicates whether the key press event
+was consumed by the handler.  You should make sure to return
+<tt>false</tt> if you do not use the given key, otherwise keyboard
+accelerators for the menu bar will no longer function correctly.
+
+<p>Note that FLTK defines
+<a
+    href="http://www.fltk.org/doc-1.0/enumerations.html#key_values">symbolic
+    names</a> for non-ASCII keys.  You can also query the state of the
+modifier keys using the <tt><a href="http://www.fltk.org/doc-1.0/enumerations.html#13_6">Fl::event_state()</a></tt> function.
+
+<h4>Animation</h4>
+
+<p>A very simple mechanism for supporting animation is also provided by the
+framework.  To take advantage of this, first set the <tt>MxGUI</tt> instance
+variable
+<pre>
+    float default_fps;
+</pre>
+to the desired number of frames per second (defaults to 24).  The method
+<pre>
+    void animate(bool will);
+</pre>
+can then be used to start and stop animation.
+The system works by setting a system timer to go off every 1/fps of a second.
+When that timer goes off, the framework will call the handler
+<pre>
+    virtual void update_animation();
+</pre>
+so that the application can update its state appropriately, after which the
+framework will invoke the <tt>draw_contents()</tt> handler to repaint the
+canvas.  Note that this system makes no effort to guarantee a consistent
+update rate.
+
+<p>The default menu bar contains items to toggle animation on and off and to
+set the desired <tt>default_fps</tt> value.
+
+
+<h3>The Menu Bar</h3>
+
+<p>Many GUI applications use menu systems to provide the user control over the
+application.  By default, the <tt>MxGUI</tt> framework creates a very simple
+menu layout for its applications.  This standard menu provides basic features
+such as saving a snapshot of the OpenGL canvas to an image file, toggling
+animation, and setting the size of the display canvas.
+However, the application also has complete freedom to customize the menu
+system.
+
+<h4>Static Menu Layouts</h4>
+
+<p>The <tt>initialize()</tt> method accepts an optional argument which
+specifies the layout of the menu system.  This layout is an array of <a
+href="http://www.fltk.org/doc-1.0/Fl_Menu_Item.html">Fl_Menu_Item</a> elements,
+whose format is described in the <a
+href="http://www.fltk.org/doc-1.0/Fl_Menu_Item.html">FLTK documentation</a>.
+Passing a menu layout to <tt>initialize()</tt> will completely replace the
+default menu structure.
+
+<h4>Adding Menus at Run Time</h4>
+
+<p>Once an initial menu system has been created, either the default or an
+application-specific one, additional items can be added at run time.  To do
+this, you can invoke the <a
+href="http://www.fltk.org/doc-1.0/Fl_Menu_.html#Fl_Menu_.add"><tt>add()</tt></a>
+method of the <tt>MxGUI::menu_bar</tt> object.
+
+
+<h3>The Status Bar</h3>
+
+<p>The status bar at the bottom of the GUI application can be used to display
+short textual messages to the user.
+You can use the following method to print text in the status bar:
+<pre>
+    int status(const char *fmt, ...);
+</pre>
+It accepts argument lists of exactly the same form as the <tt>printf</tt>
+function of the C standard library.

+<title>libgfx: Packed Integer Vectors</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>Packed Integer Vectors</h2>
+
+<p>The <a href="vec.html">vector package</a> provides the standard way to
+represent and manipulate vector quantities.
+These vectors are primarily designed to represent real-valued vectors using
+floating point numbers.
+However, there are times when it is more convenient to use a packed integer
+vector format.  That is the purpose of this package, which you can use by
+including the header file
+<pre>
+    #include &lt;intvec.h&gt;
+</pre>
+
+<p>A <em>packed integer vector</em> is an <i>n</i> element vector, each of whose
+elements are <i>k</i>-bit integers.  These <i>k</i>-bit integers are
+interpreted as representing the range [0, 1] for unsigned types and [-1, 1]
+for signed types.  For example, suppose we have a vector whose elements are
+unsigned 8-bit quantities (e.g., of type <tt>unsigned char</tt>).
+Each value would have an integral value in the range [0, 255], but these
+values would always be interpreted as real values ranging between [0, 1].
+
+<h3>class IntVec</h3>
+<p>Packed integer vectors are declared using the following template class
+<pre>
+    template&lt;class T, int T_MAX, int N&gt;  class IntVec;
+</pre>
+The type <tt>T</tt> is the type of the constituent elements (e.g.,
+<tt>unsigned char</tt>) and <tt>T_MAX</tt> is the maxium representable value
+for this type (e.g., <tt>UCHAR_MAX</tt>).  The number of elements in the
+vector is determined by <tt>N</tt>.  Note that ANSI C defines appropriate
+maximum values of integer types in &lt;limits.h&gt;.
+
+<p>Classes created from the <tt>IntVec</tt> template provide a small set of
+fundamental public methods:
+<ul>
+<li>A default constructor that initializes all elements of the vector to 0.
+
+<li>A C-style [] bracket accessor which returns, as a
+<tt>double</tt> the appropriate element of the vector.
+
+<li>A vector assignment operator (<tt>v = w</tt>).
+
+<li>A scalar assignment operator (<tt>v = 3.14</tt>).
+</ul>
+
+<h3>class IntVec3</h3>
+
+<p>Because 3-D vectors are particularly common in graphics applications, this
+package provides explicit support for them.
+<pre>
+    template &lt;class T, int T_MAX&gt;  class IntVec3;
+</pre>
+
+<p>In addition to the standard <tt>IntVec</tt> methods, <tt>IntVec3</tt>
+provides the following additional constructors, all of which allow the values
+of the vector to be explicitly initialized.
+<pre>
+    IntVec3(double x, double y, double z);
+    IntVec3(const Vec3&amp; v);
+    IntVec3(const float  v[3]);
+    IntVec3(const double v[3]);
+</pre>
+
+<p>It also provides the following methods for manipulating the elements of the
+vector:
+<pre>
+    Vec3 unpack() const;                      <i>// Return vector as Vec3</i>
+    void pack(const Vec3&amp; v);                 <i>// Set vector from v</i>
+    void pack(double x, double y, double z);  <i>// Set vector from x,y,z</i>
+</pre>
+
+<p>A typical use of this class would be in defining a type for RGB colors
+represented with 8 bits per channel.  Such a type could be declared as
+follows:
+<pre>
+    typedef IntVec3<unsigned char, UCHAR_MAX> byteColor;
+</pre>

+</head>
+
+<body>
+
+<h2>Matrix Math</h2>
+
+<p>The <tt>libgfx</tt> matrix math package is the companion to the 
+<a href="vec.html">vector package</a> and are intended to provide a convenient
+way of writing vector/matrix equations.
+Currently, only square matrices
+of dimension 2x2 [<a href="mat2.html"><tt>Mat2</tt></a>],
+3x3 [<a href="mat3.html"><tt>Mat3</tt></a>],
+and 4x4 [<a href="mat4.html"><tt>Mat4</tt></a>].
+
+<p>A matrix consists of <i>n*n</i> double precision floating point values.
+Unlike the vector package, the matrix package is not yet template-based.
+Matrix elements are accessed using 0-indexed (row, column) pairs.  Thus, a 2x2
+identity matrix can be constructed as follows:
+<pre>
+    Mat2 A;
+
+    A(0, 0) = 1.0;
+    A(0, 1) = 0.0;
+    A(1, 0) = 0.0;
+    A(1, 1) = 1.0;
+</pre>
+The default constructors (as used above) initialize all elements to 0.  All
+matrix classes also provide constructors which accept a list of row vectors to
+initialize their elements.  Thus, the following example is equivalent to the
+code above:
+<pre>
+    Mat2 A(Vec2(1.0, 0.0), Vec2(1.0, 0.0));
+</pre>
+Matrices can also be automatically case to <tt>double</tt> pointers.  Since
+matrices are stored in row-major order, the follow code would change element
+(0, 1) of the matrix above:
+<pre>
+    double *B = A;
+    B[1] = -1.0;
+</pre>
+
+<p><strong>Warning:</strong>
+For efficiency reasons, <em>accessors are not range checked</em>.
+Thus you can legally write
+<pre>
+    Mat2 v;
+    v(-10, 37) = 1.0;
+</pre>
+and generate an invalid memory access.
+
+<h3>Arithmetic Operators</h3>
+
+<p>Like the vector package, one of the primary goals of the matrix package is
+to simplify the writing of vector/matrix equations.
+To accomplish this, it makes use of C++ operator overloading.
+
+<p><strong>Assignment</strong>&nbsp;&nbsp;
+Matrices can be assigned the values of other matrices or scalars.
+A matrix assignment <tt>A = B</tt> copies the elements of <tt>B</tt>
+into the corresponding elements of <tt>A</tt>.  A scalar assignment
+<tt>A = 1.0</tt> copies the given scalar, in this case <tt>1.0</tt>,
+into each of the elements of <tt>A</tt>.
+
+<p><strong>Addition/Subtraction</strong>&nbsp;&nbsp;
+Matrices can be added together either with the binary addition operator (<tt>C
+= A + B</tt>) or the additive assignment operator (<tt>A += B</tt>).
+Subtraction operates similarly, using subtraction rather than addition
+operators.
+
+<p><strong>Scalar Multiplication/Division</strong>&nbsp;&nbsp;
+Matrices can be multiplied by scalar values using either the binary
+operator (<tt>A * 2.0</tt>) or the accumulation operator (<tt>A *=
+2.0</tt>).  Scalar division operates similarly.
+
+<p><strong>Matrix/Vector Multiplication</strong>&nbsp;&nbsp;
+Matrices can be multiplied together with a binary operator (<tt>A *
+B</tt>).  Matrices can also multiply vectors (<tt>A * v</tt>) which returns a
+new vector.
+
+<h3>Standard Matrix Functions</h3>
+
+<p>All matrix classes support a standard set of functions for performing
+common operations on matrices.  The functions are:
+<pre>
+<i>// Constructs the outer product of the two vectors</i>
+Mat_ outer_product(const Vec_ &amp;u, const Vec_ &amp;v);
+
+<i>// Returns the determinant of the matrix</i>
+double det(const Mat_ &amp;A);
+
+<i>// Returns the trace of the matrix (the sum of the diagonals)</i>
+double trace(const Mat_ &amp;A);
+
+<i>// Returns the transpose of A</i>
+Mat_ transpose(const Mat_ &amp;A);
+
+<i>// Returns the adjoint of A</i>
+Mat_ adjoint(const Mat_ &amp;A);
+
+<i>// Places the inverse of A in A_inv and returns det(A)
+// The contents of A_inv are undefined if the inverse doesn't exist.</i>
+double invert(Mat_ &amp;A_inv, const Mat_ &amp;A);
+</pre>
+
+<p>Matrices can also be read from and written to C++ iostreams using the
+standard <tt>&lt;&lt;</tt> and <tt>&gt;&gt;</tt> operators.

+
+
+<h4>Transformation Functions</h4>
+
+<p>Because 4x4 matrices are commonly used to represent linear homogeneous
+transformations in computer graphics, the matrix package provides several

+transformations as used in OpenGL.  The resulting matrices should be
+equivalent to those produced by OpenGL, to the extent allowed by limited
+floating point accuracy.
+
+<pre>

+    Mat4 translation_matrix(const Vec3&amp; delta);
+    Mat4 scaling_matrix(const Vec3&amp; scale);
+    Mat4 rotation_matrix_deg(double theta, const Vec3&amp; axis);
+    Mat4 rotation_matrix_rad(double theta, const Vec3&amp; axis);
+
+    <i>// Construct a perspective projection matrix.
+    // Direct analog of gluPerspective()</i>
+    Mat4 perspective_matrix(double fovy, double aspect,
+                            double zmin=0.0, double zmax=0.0);
+
+    <i>// Construct a viewing transformation.
+    // Direct analog of gluLookAt()</i>
+    Mat4 lookat_matrix(const Vec3&amp; from, const Vec3&amp; at, const Vec3&amp; up);
+
+    <i>// Construct a viewport mapping.
+    // Direct analog of glViewport().</i>
+    Mat4 viewport_matrix(double w, double h);
+</pre>
+
+Note that the <tt>rotation_matrix()</tt> function comes in two forms, once
+which expects an angle in <em>radians</em> and one which expects an angle in
+<em>degrees</em>.  The type of angle expected is made explicit in the function
+name (i.e., <tt>_rad</tt> and <tt>_deg</tt> suffixes) in an attempt to avoid
+confusion.

+<h2>Quaternions</h2>
+
+<p>This package provides the basic mathematical tools necessary for
+manipulating quaternions.  To begin using it, you must first include the
+header file:
+<pre>
+    #include &lt;gfx/quat.h&gt;
+</pre>
+
+<p>For more information on the definition of quaternions and their
+associated mathematics, you might try the informative Web pages provided
+by
+<a href="http://mathworld.wolfram.com/Quaternion.html">MathWorld</a>,
+<a href="http://www.magic-software.com/Documentation/quat.pdf">David
+    Eberly</a>, or
+<a
+    href="http://graphics.cs.ucdavis.edu/GraphicsNotes/Quaternions.pdf">UC
+    Davis</a>.
+
+<h3>class Quat</h3>
+
+<p>The interface presented by the <tt>Quat</tt> class treats quaternions
+as consisting of a real scalar part and a complex 3-vector part.
+
+<h4>Constructor Methods</h4>
+
+<p>The <tt>Quat</tt> class defines the following set of constructors:
+
+<pre>
+    Quat();                                        <i>// Initializes to identity quaternion</i>
+    Quat(double x, double y, double z, double w);  <i>// Specify vector &amp; scalar part.</i>
+    Quat(const Vec3&amp; a, double b);                 <i>// Specify vector &amp; scalar part.</i>
+    Quat(const Quat&amp; q);                           <i>// Copy values from q</i>
+</pre>
+
+<pre>
+    Quat::ident();                                 <i>// Return the identity quaternion</i>
+</pre>
+
+<h4>Arithmetic Methods</h4>
+
+<p>The quaternion class supports all the usual arithmetic methods, both
+as in-place assignment operators:
+
+<pre>
+    Quat&amp; operator=(const Quat&amp; q);
+    Quat&amp; operator+=(const Quat&amp; q);
+    Quat&amp; operator-=(const Quat&amp; q);
+    Quat&amp; operator=(double d);
+    Quat&amp; operator*=(double d);
+    Quat&amp; operator/=(double d);
+</pre>
+
+and as normal binary operations:
+
+<pre>
+    Quat operator+(const Quat&amp; q, const Quat&amp; r);
+    Quat operator*(const Quat&amp; q, const Quat&amp; r);
+    Quat operator*(const Quat&amp; q, double s);
+    Quat operator*(double s, const Quat&amp; q);
+    Quat operator/(const Quat&amp; q, double s);
+</pre>
+
+<h4>Quaternion Operations</h4>
+
+<p>Using the fundamental arithmetic operations defined above, this
+package also provides the following operations on quaternions:
+<pre>
+    double norm(const Quat&amp; q);     <i>// Return the length of q</i>
+    Quat conjugate(const Quat&amp; q);  <i>// Return conjugate of q</i>
+    Quat inverse(const Quat&amp; q);    <i>// Return multiplicative inverse of q</i>
+    void unitize(Quat&amp; q);          <i>// Convert to unit quaternion</i>
+    Quat exp(const Quat&amp; q);        <i>// Exponential of a <b>unit</b> quaternion </i>
+    Quat log(const Quat&amp; q);        <i>// Natural logarithm of a <b>unit</b> quaternion </i>
+</pre>
+
+<p>Quaternions can be constructed from an axis/angle rotation
+specification using the function:
+<pre>
+    Quat axis_to_quat(const Vec3&amp; a, double phi);
+</pre>
+At is also generally useful to be able to convert a quaternion into a
+rotation matrix:
+<pre>
+    Mat4 quat_to_matrix(const Quat&amp; q);
+    Mat4 unit_quat_to_matrix(const Quat&amp; q);
+</pre>
+
+<p>
+<pre>
+    Quat slerp(const Quat&amp; from, const Quat&amp; to, double t);
+</pre>
+
+<p>Quaternions can also be read from and written to C++ iostreams using the
+standard <tt>&lt;&lt;</tt> and <tt>&gt;&gt;</tt> operators.

+<title>libgfx: Raster Images</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>Raster Images</h2>
+
+<p>The <tt>libgfx</tt> library provides very basic support for storing raster
+image data.  This is not really intended to provide the kind of support
+necessary for advanced image processing, but rather the basic functionality
+needed for saving screen snapshots, loading texture files, etc.  To use this
+package you will first need to include the header file
+<pre>
+    #include &lt;gfx/raster.h&gt;
+</pre>
+
+<h3>Image Representation</h3>
+
+<p>Images are implemented using the <tt>Raster&lt;T&gt;</tt> template class.
+The templated type <tt>T</tt> determines how individual pixel values are
+stored.  There are two standard image types:
+<ul>
+<li><tt>ByteRaster</tt>:
+pixel components are represented with values of type <tt>unsigned
+char</tt>
+
+<li><tt>FloatRaster</tt>:
+pixel components are represented with values of type <tt>float</tt>
+</ul>
+
+<h4>Allocating an Image</h4>
+
+<p>When allocating an image, you must specify its three dimensions: (1) width
+in pixels, (2) height in pixels, and (3) number of channels.
+<pre>
+    Raster&lt;T&gt;(int width, int height, int nchannels);
+</pre>
+Typically, the number of channels should by either 1 for grayscale images, 3
+for RGB color images, or 4 for RGB images with an alpha channel.
+
+<h4>Accessors</h4>
+
+<p>The dimensions of an image can be determined through a standard set of
+accessor functions:
+<pre>
+    int width();      <i>// Width of image (in pixels)</i>
+    int height();     <i>// Height of image (in pixels)</i>
+    int channels();   <i>// Number of channels in image</i>
+    int length();     <i>// Total number of pixel values</i>
+</pre>
+The width, height, and channel count values are merely those specified when
+the image is allocated.  The length of the image is the total number of pixel
+elements (i.e., width*height*channels).
+
+<p>Pixel elements can be accessed in two different ways.  First of all, you
+can get a pointer to the single pixel at the image location (i,j) by calling
+the method
+<pre>
+    T  *pixel(int i, int j);
+</pre>
+This is the standard way to access pixels.  Alternatively, you can access
+pixel elements using the standard C [] bracket notation.  This method is
+generally discouraged since it exposes the underlying layout of the image.
+However, it can be useful if you want to visit every pixel element without
+regard to its location.
+
+
+<h4>Pixel Manipulation</h4>
+
+<p>The <tt>Raster</tt> template class provides some very simple methods for
+manipulating the image which it stores.  They are:
+<pre>
+    void hflip();   <i>// Flip the image from left to right</i>
+    void vflip();   <i>// Flip the image from top to bottom</i>
+</pre>
+
+
+<h3>Input/Output of Image Files</h3>
+
+<p>In addition to internal image representation, this package provides a
+simple set of functions for reading and writing external image files.
+The library supports the following image types:
+<ul>
+<li>PNM (supported internally)
+<li>TIFF (requires <a href="http://www.libtiff.org">libtiff</a>)
+<li>JPEG (requires <a href="http://www.ijg.org">jpeglib</a>)
+<li>PNG (requires <a href="http://www.libpng.org/pub/png/">libpng</a>)
+</ul>
+
+<p>Images can be read from files using the following functions:
+<pre>
+    ByteRaster *read_pnm_image(const char *filename);
+    ByteRaster *read_tiff_image(const char *filename);
+    ByteRaster *read_png_image(const char *filename);
+    ByteRaster *read_jpeg_image(const char *filename);
+</pre>
+These functions return <tt>NULL</tt> if the file could not be read.  This
+includes the case when the required external libraries are not available.
+Similar functions can be used to write images to files:
+<pre>
+    bool write_pnm_image(const char *filename, const ByteRaster&);
+    bool write_tiff_image(const char *filename, const ByteRaster&);
+    bool write_png_image(const char *filename, const ByteRaster&);
+    bool write_jpeg_image(const char *filename, const ByteRaster&);
+</pre>
+They return <tt>true</tt> or <tt>false</tt> indicating whether the output
+operation succeeded or not.
+
+<p>The PNM output routines can output both raw (i.e., binary) and ASCII image
+files.  Which type of file they write is controlled by the global variable
+<pre>
+    bool will_write_raw_pnm;
+</pre>
+Since JPEG is a lossy compression format, the behavior of the JPEG output
+routines is dependent upon the global variable controlling image quality
+<pre>
+    int jpeg_output_quality;
+</pre>
+These quality factors are integers ranging from 0-100 (with 100 being the
+highest quality).  See the <tt>jpeglib</tt> documentation for further details.
+
+<p>For convenience, you can read/write image files with the functions
+<pre>
+    bool write_image(const char *filename, const ByteRaster&, int type=-1);
+    ByteRaster *read_image(const char *filename, int type=-1);
+</pre>
+The file format will be inferred from the filename, unless the optional
+<tt>type</tt> argument is given.  The image type should be one of
+<tt>IMG_PNM</tt>, <tt>IMG_PNG</tt>, <tt>IMG_TIFF</tt>, or <tt>IMG_JPEG</tt>.

+<title>libgfx: Interactive Rotation Control</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>Interactive Rotation Control</h2>
+
+<p>The <tt>libgfx</tt> library provides a fairly simple facility for
+interactive inspection of 3-D objects.  The interface is designed
+for applications where a user is inspecting an object by spinning it and
+by translating the camera to provide a better view.  All of the user
+interaction is implemented through mouse motion:
+<ul>
+    <li>Left mouse drag &mdash; rotate object about its centroid
+    <li>Right mouse drag &mdash; translate camera forward/backward
+    <li>Middle mouse drag &mdash; translate camera parallel to image plane
+</ul>
+
+<p>The classes used to implement this functionality are based on a
+fairly standard paradigm.  Two subsequent mouse positions are projected
+onto a notional surface "below" the window.  The cross product of these
+projected vectors defines an axis of rotation and the angle between them
+defines the rotation angle.
+
+<h3>Ball Types</h3>
+
+<p>The library currently supports two control classes:
+
+<blockquote>
+
+<p><b>Arcball</b>&nbsp;&nbsp;The Arcball controller is based on the
+article <i>Arcball Rotation Control</i> written by Ken Shoemake in
+<i>Graphics Gems IV</i> published by Academic Press.
+The underlying surface of projection is a hemisphere.
+
+<p><b>Trackball</b>&nbsp;&nbsp;Implements the mechanism used in the SGI
+3-D demo programs.  This approach was originally developed by Gavin
+Bell.  The underlying surface of projection is a hybrid of a hemisphere
+and a hyperbolic sheet.
+</blockquote>
+
+<h3>Public Interface</h3>
+
+<p>The two controller types both implement the same public interface,
+and can be freely interchanged in the application program.  The
+interfaces for these controllers are defined in the following header
+files:
+<ul>
+    <li><tt>class Arcball</tt> &mdash; <tt>&lt;gfx/arcball.h&gt;</tt>
+    <li><tt>class Trackball</tt> &mdash; <tt>&lt;gfx/trackball.h&gt;</tt>
+</ul>
+To use one of the controllers, you need to include the appropriate
+header and create an instance of the appropriate class.
+
+<h4>Initialization</h4>
+
+<p>Before using a rotation controller, you must initialize it by
+providing the bounding sphere of the object to be controlled.  This is
+done using the templated method:
+<pre>
+    template&lt;class T&gt;
+    void bounding_sphere(const TVec3&lt;T&gt;&amp; center, T radius);
+</pre>
+The specified sphere <tt>center</tt> will be the point about which the
+object will rotate.
+
+<h4>Interaction</h4>
+
+<p>Once initialized, the controller is meant to be interfaced directly
+with the event handlers of an application built using the
+<tt>libgfx</tt> <a href="gui.html">GUI framework</a>.
+Each of the following controller methods should be called from the event
+handlers of your application.
+<pre>
+    virtual void update_animation();
+    virtual bool mouse_down(int *where, int which);
+    virtual bool mouse_up(int *where, int which);
+    virtual bool mouse_drag(int *where, int *last, int which);
+</pre>
+
+<h4>Applying Results</h4>
+
+<p>For the rotation to take effect, you must apply it in the rendering
+loop of the application.  Before drawing your scene, you should call the
+method:
+<pre>
+    virtual void apply_transform();
+</pre>
+This will set up the appropriate transform on the <tt>ModelView</tt>
+matrix stack.  Similarly, when done drawing, you should call the method:
+<pre>
+    virtual void unapply_transform();
+</pre>
+which will clean up the <tt>ModelView</tt> matrix stack.

+<title>libgfx: Simple File Format Scripting</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>Simple File Format Scripting</h2>
+
+<p>The <tt>libgfx</tt> library provides a very simple scripting facility which
+is primarily intended to support parsing of input files and control scripts.
+To use this package, you must include the header file:
+<pre>
+    #include &lt;gfx/script.h&gt;
+</pre>
+
+<p>For more information about this package, you may want to examine the
+sample <a href="ex-script.html">scripted application</a>.
+
+<h3>File Structure</h3>
+
+<p>Scripts processed by this package are assumed to be composed of a sequence
+of lines.  Each line is processed separately, in sequence, and falls into one
+of the following categories:
+<ol>
+<li>Lines containing only whitespace are ignored
+<li>Lines whose first non-whitespace character is a '#' (hash mark) are
+treated as comments and are ignored
+<li>All other lines are assumed to be a sequence of whitespace-separated
+tokens where the first token is a command name and subsequent tokens are
+arguments to this command.
+</ol>
+
+<h3>Processing Scripts</h3>
+
+<p>In order to process scripts, you must (at minimum) perform the following
+steps:
+<ol>
+<li>Instantiate a <i>scripting environment</i> of type <tt>CmdEnv</tt>.
+<li>Register your command(s) with <tt>CmdEnv::register_command()</tt>
+or <tt>CmdEnv::register_method()</tt>.
+<li>Feed the text of the script to the parsing system.
+</ol>
+The specifics of these steps are detailed in the following sections.
+
+<h4>The Scripting Environment</h4>
+
+<p>The primary task of the scripting system is to map command name tokens into
+command procedures.  These procedures, also referred to as "handlers", are
+responsible for actually performing the computation associated with a
+particular command.
+Handlers should conform to the following type definition:
+<pre>
+    typedef int (*CmdHandler)(const CmdLine &amp;cmd);
+</pre>
+The <tt>CmdLine</tt> type manages the text of a particular command line, and
+provides various methods for parsing that information (see details below).
+
+<p>The <tt>CmdEnv</tt> class manages the mapping of command names to
+handlers.  In particular, handler names are mapped to pointers to
+objects derived from the base class <tt>CmdObject</tt>.  All derived
+classes of <tt>CmdObject</tt> are required to override the
+<tt>operator()</tt> invocation virtual method.  By using this virtual
+function, handler objects are allowed to encapsulate arbitrary data in
+their definition (i.e., to create closures).  The standard scripting
+framework defines two kinds of <tt>CmdObject</tt> handlers: (1) the
+<tt>CmdFunction</tt> class to encapsulate normal functions and static
+methods and (2) and the <tt>CmdMethod</tt> template class to
+encapsulate member functions.
+
+
+<p>New handler procedures (non-member functions)
+can be associated with names using
+the method:
+<pre>
+    void register_command(const std::string&amp; name, CmdHandler proc);
+</pre>
+Member functions can be bound to names uses the templated member
+function:
+<pre>
+    template&lt;class T&gt;
+    void register_method(const std::string& name,
+                         T *obj,
+                         int (T::*fn)(const CmdLine&));
+</pre>
+Note that in both cases, prior bindings of <tt>name</tt> associated
+with another handler will be overwritten.
+Existing handlers can be located by name
+using the method:
+<pre>
+    CmdObject *lookup_command(const std::string&amp; name);
+</pre>
+which returns <tt>NULL</tt> if no handler is bound to the given name.
+
+<h4>Submitting Text for Execution</h4>
+
+<p>Several procedures are available for submitting script text to the parsing
+system.  All of them require a <tt>CmdEnv</tt> argument that will determine
+the mapping of command names to handlers.
+
+<p>The underlying method for parsing text is:
+<pre>
+    int script_do_line(std::string &amp;line, CmdEnv &amp;env);
+    int script_do_line(const char *line, CmdEnv &amp;env);
+</pre>
+It assumes that its input is a string consisting of a single line &mdash; any
+embedded newlines will be treated like any other whitespace.
+It will
+split this line it a series of whitespace-separated tokens, interpreting the
+first such token as a command name.  If <tt>env</tt> provides a binding for
+this name, the appropriate handler will be called.
+
+<p>For convenience, the scripting package also provides the following methods:
+<pre>
+    int script_do_stream(std::istream &amp;in, CmdEnv &amp;env);
+    int script_do_file(const char *name, CmdEnv &amp;env);
+    int script_do_string(const char *str, CmdEnv &amp;env);
+</pre>
+They operate by extracting a single line from the input source and processing
+that line with <tt>script_do_line()</tt>.  They repeat this line-by-line
+process until the file/stream/string has been exhausted.
+The first time the processing of a line fails with an error code, these
+procedures return this error code immediately without completing the
+processing of the rest of the input.
+
+
+<h3>Writing Command Handlers</h3>
+
+<p>A command procedure is declared as follows:
+<pre>
+    int proc(const CmdLine&amp; cmd);
+</pre>
+The <tt>CmdLine</tt> structure contains all the necessary data about the line
+being processed.  It provides the following fundamental accessors:
+<pre>
+    class CmdLine
+    {
+    public:
+	const std::string &amp;line;        // Raw text of the (complete) line
+	std::string opname() const;     // Name of the command being invoked
+	std::string argline() const;    // Argument string
+	int argcount() const;           // Number of argument tokens
+    };
+</pre>
+The argument string returned by <tt>argline()</tt> is unparsed except that
+whitespace following the command name and trailing whitespace at the end of
+the line have been removed.
+
+
+<p>It is up to the handler to parse the command line in whatever way it likes.
+However, the scripting system assumes that command will be given
+whitespace-separated token lists.  Therefore, it pre-computes the indices of
+these tokens in the command line text before invoking the handler.  To access
+an individual token, you can use the <tt>CmdLine</tt> methods:
+<pre>
+    std::string token_to_string(int i) const;
+    double token_to_double(int i) const;
+    float token_to_float(int i) const;
+    int token_to_int(int i) const;
+</pre>
+Tokens are numbered from <tt>[0 .. argcount()-1]</tt>.  Note that, for
+efficiency, these methods <em>do not perform range checking.</em>  It is up to
+the caller to verify that the given indices are valid.
+
+<p>In addition to accessing single argument tokens, you can collect all
+argument tokens into lists with the following <tt>CmdLine</tt> methods:
+<pre>
+    int collect_as_strings(std::vector&lt;std::string&gt; &amp;v) const;
+    int collect_as_numbers(std::vector&lt;double&gt; &amp;v) const;
+    int collect_as_numbers(std::vector&lt;int&gt; &amp;v) const;
+
+    int collect_as_numbers(double *v, int size) const;
+    int collect_as_numbers(float *v, int size) const;
+    int collect_as_numbers(int *v, int size) const;
+</pre>
+These methods always return the number of tokens collected.
+The <tt>vector</tt>-based methods will always collect all available tokens.
+In contrast, those which accept raw arrays will either collect <tt>size</tt>
+or <tt>argcount()</tt> tokens, whichever is smaller.
+
+<p>See the accompanying <a href="ex-script.html">scripting example</a> for more
+details on how to write command handlers.

+<title>libgfx: Getting Started</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>Getting Started </h2>
+
+<p>The <tt>libgfx</tt> library can be used for writing both
+console-oriented and GUI programs.  All programs, whether console or
+GUI, should begin by including the standard header:
+<pre>
+    #include &lt;gfx/gfx.h&gt;
+</pre>
+
+<h3>The Standard Header: gfx.h</h3>
+
+<p>The first task of the standard header file is to provide a consist
+code environment.  It begins by including a set of standard C++
+headers <tt>&lt;cstdlib&gt;</tt>, <tt>&lt;cmath&gt;</tt>,
+<tt>&lt;climits&gt;</tt>, and <tt>&lt;iostream&gt;</tt>.
+It then makes sure that various common symbols, such as <tt>bool</tt>,
+<tt>M_PI</tt>, and <tt>HUGE</tt> are defined.
+
+<h4>Numerical Procedures</h4>
+
+<p>Graphics programs typically involve a substantial amount of
+mathematical calculation.  Indeed, much the the <tt>libgfx</tt>
+library is devoted to supporting things such as matrix/vector
+computations.  Certain mathematical procedures are common enough, and
+simple enough, that they are included in the standard header.
+
+<p>First, there are the procedures for generating random numbers:
+<pre>
+    inline double random1();        <i>// Random number between 0 and 1</i>
+    inline char   random_byte();    <i>// Random byte between 0 and 255</i>
+</pre>
+These functions use the internal <tt>random()</tt> procedure if it's
+available, or <tt>rand()</tt> if not.
+
+<p>Next, are procedures for comparing floating point numbers:
+<pre>
+    const double FEQ_EPS = 1e-6;
+    const double FEQ_EPS2 = 1e-12;
+
+    inline bool  FEQ(double a, double b, double eps=FEQ_EPS);
+    inline bool  FEQ2(double a, double b, double eps=FEQ_EPS2);
+</pre>
+The <tt>FEQ()</tt> procedures return <tt>true</tt> if <tt>a</tt> and
+<tt>b</tt> are within <tt>eps</tt> of each other.
+
+<h4>Timing Procedures</h4>
+
+<p>To characterize the performance of a program, it is often useful to
+measure it's running time.  For this reason, <tt>libgfx</tt> provides
+some basic facilities for measuring time.
+
+<pre>
+    extern double get_cpu_time();
+</pre>
+
+The function returns the number of seconds on the CPU clock.  Based on
+the platform you're using, this function may use various system
+services to compute this clock.  Therefore, it does not use a
+consistent measure across all systems; however, the returned quantity
+will usually be the number of seconds since the system was turned on.
+
+<p>A more convenient way to measure running time is to use the
+following macro:
+<pre>
+    #define TIMING(t, cmd) { t=get_cpu_time(); cmd; t=get_cpu_time() - t; }
+</pre>
+Given a procedure <tt>test_proc()</tt> whose performance we want to
+measure, we can use the following code:
+<pre>
+    double running_time;
+
+    TIME(running_time, test_proc());
+
+    cout << "The running time was: " << running_time << " seconds." << endl;
+</pre>
+This will print the running time of <tt>test_proc()</tt> on the console.
+
+
+<h4>Configuration Definitions</h4>
+
+<p>The final task of the standard header is to include the
+<tt>libgfx</tt> configuration header.  This header is generated when
+the library is compiled.  On Unix-like platforms, the header is named
+<tt>&lt;gfx/config.h&gt;</tt> and is generated automatically by the
+configuration script.  For Microsoft Visual Studio platforms, a
+hand-coded header such as <tt>&lt;gfx/config-vc5.h&gt;</tt> is used
+instead.  The symbols defined in this header can be used to detect the
+presence of various language features and external libraries.
+The symbols of interest to external programs are summarized below:
+
+<br><br>
+<table align=center width=85% border=0 cellpadding=5>
+<tr valign=top><th align=left>Symbol</th><th align=left>Defined when ...</th></tr>
+
+<tr valign=top><td><tt>HAVE_LIBTIFF</tt></td>
+<td>library supporting TIFF image I/O is available.</td></tr>
+
+<tr valign=top><td><tt>HAVE_LIBTIFF_LZW</tt></td>
+<td><tt>libtiff</tt> supports patented LZW compression.</td></tr>
+
+<tr valign=top><td><tt>HAVE_LIBPNG</tt></td>
+<td>library supporting PNG image I/O is available.</td></tr>
+
+<tr valign=top><td><tt>HAVE_LIBJPEG</tt></td>
+<td>library supporting JPEG image I/O is available.</td></tr>
+
+<tr valign=top><td><tt>HAVE_OPENGL</tt></td>
+<td>OpenGL is available.  Value is name of implementation
+(e.g., "OpenGL" or "Mesa").</td></tr>
+</table>
+
+<p>These configuration symbols should be tested with <tt>#ifdef</tt>
+directives, as in the following example:
+<pre>
+    #ifdef HAVE_LIBTIFF
+    generate_tiff_output();
+    #endif
+</pre>
+
+</body>

+<title>libgfx: Vector Math</title>
+<link rel=stylesheet href="cdoc.css" type="text/css">
+<meta name="Author" content="Michael Garland">
+</head>
+
+<body>
+
+<h2>Vector Math</h2>
+
+<p>The <tt>libgfx</tt> vector math package provides classes that 
+make it much more convenient to write vector equations.
+Two dimensional [<a href="vec2.html">Vec2</a>],
+three dimensional [<a href="vec3.html">Vec3</a>],
+and four dimensional [<a href="vec4.html">Vec4</a>]
+vector classes are provided.
+
+<p>A vector consists of <i>n</i> numeric values.  These vector types are
+actually implemented using template classes such as <tt>TVec3&lt;class
+T&gt;</tt> that allow the application to specify the type of value used to
+represent the vector elements.  The standard classes described in this
+documentation (<tt>Vec2</tt>, <tt>Vec3</tt>, and <tt>Vec4</tt>) use double
+precision floating point values.  Corresponding classes using single precision
+floating point values (<tt>Vec2f</tt>, <tt>Vec3f</tt>, and <tt>Vec4f</tt>) are
+also provided.
+
+<p>The elements of a vector are accessed with the standard bracket notation
+used for arrays.  And like C++ arrays, vectors are indexed starting from 0.
+Thus the elements of a 3-vector can be assigned as follows:
+
+<pre>
+    Vec3 v;
+
+    v[0] = 1.0;
+    v[1] = 0.0;
+    v[2] = 2.0;
+</pre>
+
+The default constructors (as used in the previous example) always
+initialize the vector elements to 0.  All vector classes also provide
+constructors which accept the initial element values as arguments.
+Thus the previous example could be more succinctly written as:
+
+<pre>
+    Vec3 v(1.0, 0.0, 2.0);
+</pre>
+
+Vectors can also be automatically cast to <code>double</code> pointer
+types.  Continuing the preceding example, the following is perfectly legal:
+<pre>
+    double *w = v;     <i>// w points to the first element of v</i>
+    w[1] = 3.14;       <i>// Exactly equivalent to v[1] = 3.14</i>
+</pre>
+
+<p><strong>Warning:</strong>
+For efficiency reasons, <em>accessors are not range checked</em>.
+Thus you can legally write
+
+<pre>
+    Vec3 v;
+    v[42] = 3.14159;
+</pre>
+
+and this will cause an invalid memory access beyond the bounds of the
+vector.  This may cause a memory fault or it may just silently
+over-write other data.  Therefore you must make sure that you only
+access valid elements of arrays.
+
+
+<h3>Arithmetic Operators</h3>
+
+<p>One of the primary goals of the vector package is to simplify the
+coding of vector equations.  To accomplish this, it makes use of
+<em>operator overloading</em>.
+
+
+<p><strong>Assignment</strong>&nbsp;&nbsp;
+Vectors can be assigned the values of other vectors or scalars.
+A vector assignment <tt>v = w</tt> copies the elements of <tt>w</tt>
+into the corresponding elements of <tt>v</tt>.  A scalar assignment
+<tt>v = 1.0</tt> copies the given scalar, in this case <tt>1.0</tt>,
+into each of the elements of <tt>v</tt>.
+
+<p><strong>Addition/Subtraction</strong>&nbsp;&nbsp; Vectors can be
+added together either with the binary addition operator (<tt>u = v +
+w</tt>) or the additive assignment operator (<tt>u += v</tt>).
+Subtraction operates similarly, using subtraction rather than addition
+operators.
+
+<p><strong>Scalar Multiplication/Division</strong>&nbsp;&nbsp;
+Vectors can be multiplied by scalar values using either the binary
+operator (<tt>v * 2.0</tt>) or the accumulation operator (<tt>v *=
+2.0</tt>).  Scalar division operates similarly.
+
+<p><strong>Inner Product</strong>&nbsp;&nbsp;
+The inner product (or dot product) of two vectors is written with the
+standard multiplication operator: <tt>v * w</tt>.
+
+<h3>Standard Vector Functions</h3>
+
+<p>All vector classes support a standard set of functions for
+performing common operations on vectors.  These functions are:
+<pre>
+    <i>// Returns the squared length of the vector v</i>
+    inline double norm2(const Vec_& v);
+
+    <i>// Returns the length of the vector v</i>
+    inline double norm(const Vec_& v);
+
+    <i>// Adjusts v to have unit length.  Mostly equivalent to v/=norm(v)</i>
+    inline void unitize(Vec_& v);
+</pre>
+
+<p>Vector can also be read from and written to C++ iostreams using the
+standard <tt>&lt;&lt;</tt> and <tt>&gt;&gt;</tt> operators.

+ * vroot.h -- Virtual Root Window handling header file
+ *
+ * This header file redefines the X11 macros RootWindow and DefaultRootWindow,
+ * making them look for a virtual root window as provided by certain `virtual'
+ * window managers like swm and tvtwm. If none is found, the ordinary root
+ * window is returned, thus retaining backward compatibility with standard
+ * window managers.
+ * The function implementing the virtual root lookup remembers the result of
+ * its last invocation to avoid overhead in the case of repeated calls
+ * on the same display and screen arguments. 
+ * The lookup code itself is taken from Tom LaStrange's ssetroot program.
+ *
+ * Most simple root window changing X programs can be converted to using
+ * virtual roots by just including
+ *
+ * #include <X11/vroot.h>
+ *
+ * after all the X11 header files.  It has been tested on such popular
+ * X clients as xphoon, xfroot, xloadimage, and xaqua.
+ * It also works with the core clients xprop, xwininfo, xwd, and editres
+ * (and is necessary to get those clients working under tvtwm).
+ * It does NOT work with xsetroot; get the xsetroot replacement included in
+ * the tvtwm distribution instead.
+ *
+ * Andreas Stolcke <[email protected]>, 9/7/90
+ * - replaced all NULL's with properly cast 0's, 5/6/91
+ * - free children list (suggested by Mark Martin <[email protected]>), 5/16/91
+ * - include X11/Xlib.h and support RootWindowOfScreen, too 9/17/91
+ *
+ * Jamie Zawinski <[email protected]>, 28-Apr-1997
+ * - use ANSI C
+ *
+ * Jamie Zawinski <[email protected]>, 3-Sep-2003
+ * - if the environment variable "XSCREENSAVER_WINDOW" is set, use that
+ *   as the root window instead of searching for __SWM_VROOT.
+ *
+ * Jamie Zawinski <[email protected]>, 14-Aug-2004
+ * - changes to get gcc to stop whining about "type punning".
+ *
+ * Jamie Zawinski <[email protected]>, 16-Dec-2004
+ * - fixed that last fix.
