*** PLEASE SEE THE GIT COMMIT LOG FOR NEWER CHANGES ***

2009-01-14  Fridrich Strba  <[email protected]>

	* gen_art_config.c: remove
	* gen_art_config.sh.in: add
	* configure.in, Makefile.am: use a shell script together
	with autotools to create the art-config.h. This way is cross-compile
	friendly and gives the same result.

2008-01-30  Alexander Larsson  <[email protected]>

	* configure.in:
	* NEWS: 
	Release 2.3.20

2007-03-01  Frederic Crozat  <[email protected]>

	reviewed by: Dom Lachowicz <[email protected]>

	* art_misc.h: Fix header when included in C++.
	Patch from Goetz Waschk and Laurent Montel.

2007-02-28  Kjartan Maraas  <[email protected]>

	configure.in: Release 2.3.19

2007-02-28  Kjartan Maraas  <[email protected]>

	* configure.in: Fix a typo introduced with the bug fix
	for bug #131478. Noticed by Yanko Kaneti.

2007-02-26  Kjartan Maraas  <[email protected]>

	* configure.in: 2.3.18.

2006-12-06  Kjartan Maraas  <[email protected]>

	* .cvsignore:
	* Makefile.am:
	* autogen.sh:
	* configure.in:
	Port to automake 1.9. Patch from Christian Persch.
	Closes bug #131478

2005-10-26  Alexander Larsson  <[email protected]>

	* Makefile.am:
	* configure.in:
	Cygwin build fixes from Cygwin Ports maintainer (#317562)

2005-10-05  Dom Lachowicz <[email protected]>

	* art-misc.[ch]: Turn memory-managing macros into proper functions
	instead of preprocessor wrappers around malloc. Win32 ships multiple 
	runtimes, and an art_alloc'd block from one runtime can't be 
	art_free'd by a different runtime.

	* libart.def: Export the 3 new functions
	
2005-05-27  Alexander Larsson  <[email protected]>

	* art_vpath_bpath.c: (art_vpath_render_bez):
	Handle the case where start and endpoint are very near
	in a better way. (#301750)

	Patch from Bernhard Herzog  

2005-03-24  Tor Lillqvist  <[email protected]>

	* art_misc.h (ART_GNUC_PRINTF, ART_GNUC_NORETURN): Use __format__,
	__printf__ and __noreturn__ to avoid warnings in case "format",
	"printf" or "noreturn" are #defined to something else. For example
	GNU libintl.h (at least some versions of it) #defines printf as
	libintl_printf.

2005-01-24  Kjartan Maraas  <[email protected]>

	* art_render_gradient.c: (art_render_gradient_radial_render):
	* testart.c:
	* testuta.c: (main): Fix some compiler warnings etc.

2005-01-21  Kjartan Maraas  <[email protected]>

	* Release 2.3.17

2004-03-22  Michael Meeks  <[email protected]>

	* Makefile.am (EXTRA_DIST): add libart.def.

2004-03-04  Glynn Foster  <[email protected]>

	* Makefile.am, configure.in, libart-2.0-uninstalled.pc.in:
	Add uninstalled pkg-config file.

Tue Sep 09 16:30:31 2003  George Lebl <[email protected]>

	* Release 2.3.16

	* art_render_gradient.c: revert the double comparison test in the
	  asserts and comment out the two asserts causing crashes
	  everywhere, see bug #121850

2003-09-02  Alexander Larsson  <[email protected]>

	* configure.in: 2.3.15

2003-08-26  Morten Welinder  <[email protected]>

	* art_render_gradient.c (art_render_gradient_linear_render_8): Fix
	vertical gradients.  Fix yet more floating point comparisons using
	!=.  For the record, Gnumeric is a heavy user.

2003-08-14  Tor Lillqvist  <[email protected]>

	Some nitpicking changes for Win32:

	* libart-features.h.in: Declare the variables from the library as
	dlimport/dllexport on Win32.

	* Makefile.am: Don't use -lm on Win32. Use the libart.def file.

	* makefile.msc: Update to generate same name DLL and import
	library as auto* and libtool. Add missing objects. (But dunno if
	it is useful to maintain this file. It isn't distributed in the
	source tarballs (should it be?). And, if it were distributed, and
	the intention was to support random people really building libart
	with MSVC, one should distribute also prebuilt config.h(.win32)
	and libart-features.h(.win32) files.)

	* libart-zip.in (DEVZIP): Fix typo.
	(DLLDIR): libtool 1.5 installs DLLs in $(prefix)/bin, so look
	there, too.

	* libart.def: Add missing entry points.

	* testuta.c: To check that the export/import of the version
	variables work, print out them in a comment. Undefine
	LIBART_COMPILATION before including libart-features.h.

2003-08-08  Alexander Larsson  <[email protected]>

	* configure.in: 2.3.14

Fri Jul 25 12:29:35 2003  George Lebl <[email protected]>

	* art_render_gradient.c (art_render_gradient_linear_render_8)
	  (art_render_gradient_linear_render) (art_render_gradient_linear)
	  (art_render_gradient_radial_render) (art_render_gradient_radial):
	  Redo the checks where float was compared by == or != to using
	  the EPSILON define.  Also copy the ArtGradientLinear and
	  ArtGradientRadial into the source structure, pretending that
	  these are constants that will never change or be freed by
	  the caller is utterly evil and in fact for librsvg it is
	  not constant.  This fixes some more very random crashes
	  when using librsvg with libart (which seems to be the
	  only usage of the gradient stuff)

Fri Jul 18 12:57:36 2003  George Lebl <[email protected]>

	* art_render_gradient.c: Fix more comparison-of-doubles by == bugs,
	  this code is uber ugly.  Should fix the fairly random crashes
	  on asserts I've been having.

2003-07-11  Michael Meeks  <[email protected]>

	* Version 2.3.13

2003-07-11  Federico Mena Quintero  <[email protected]>

	* art_svp_ops.c (art_svp_minus): impl.

Tue Jul 08 01:15:02 2003  George Lebl <[email protected]>

	* art_render_gradient.c: fix comment as pointed out by alex

Tue Jul 08 01:13:48 2003  George Lebl <[email protected]>

	* art_render_gradient.c (art_render_gradient_linear_render_8):
	  when we wish to find the current segment and we go beyond the
	  last stop due to float fun, use the last segment as that's
	  really what we want.  Avoids a very abrupt assert death.

2003-05-05  Alexander Larsson  <[email protected]>

	* configure.in:
	Bump to 2.3.12

2003-04-24  Alexander Larsson  <[email protected]>

	* art_uta_vpath.c (art_uta_from_vpath):
	Don't silently stomp on memory on bad vpaths.

2003-04-11  Alexander Larsson  <[email protected]>

	* art_svp_vpath_stroke.c (render_seg):
	Handle cases when dmr2 is very small better.

2003-04-10  Alexander Larsson  <[email protected]>

	* art_svp_wind.c (x_order_2):
	Handle horizontally aligned segments.

2002-11-25  Alexander Larsson  <[email protected]>

	* configure.in: Bump to 2.3.11

2002-10-16  John Harper  <[email protected]>

	* art_render_svp.c (art_render_svp_callback,
	art_render_svp_callback_span, art_render_svp_callback_opacity,
	art_render_svp_callback_opacity_span): if no runs would
	normally be emitted, but start is greater than zero, emit a
	single run covering the entire width of the rendered region

2002-08-18  Havoc Pennington  <[email protected]>

	* autogen.sh: hardcode aclocal-1.4/automake-1.4 so that users with
	both automake 1.6 and 1.4 installed get the right automake. Means
	compilation from CVS will now require the latest automake 1.4
	release, or manually creating symlinks called "automake-1.4" and
	"aclocal-1.4"

2002-07-01  Alexander Larsson  <[email protected]>

	* Release 2.3.10

2002-07-01  Alexander Larsson  <[email protected]>

	* configure.in (LIBART_VERSION_INFO):
	Bump to 2.3.10

	* art_svp_intersect.c (art_svp_intersect_add_seg):
	Initialize seg->wind_left to zero, this avoids
	uninitialized memory read later in art_svp_intersect_horiz_commit.

2002-06-24  Alexander Larsson  <[email protected]>

	Release 2.3.9.
	
2002-06-24  Alexander Larsson  <[email protected]>

	* configure.in: Bump to 2.3.9

2002-06-04  Balamurali Viswanathan <[email protected]>

	* Makefile.am: Added -lm to libart_lgpl_2_la_LIBADD
	fixes bug 75711 (Jacob's suggestion)

2002-05-08  Raph Levien  <[email protected]>

	* art_uta_vpath.c (art_uta_add_line): Fixes very subtle
	edge case found by Federico Mena Quintero: (96, 96) -
	(96.220200017562348, 93.034868598919431). Previously, through
	numerical error, xn was a hair to the left, throwing off
	the Bresenham iteration.

2002-03-08  Tor Lillqvist  <[email protected]>

	* configure.in: Minor changes for build on Win32. Call
	AC_LIBTOOL_WIN32_DLL. Set automake conditionals OS_WIN32 and
	MS_LIB_AVAILABLE.

	* art_affine.c: Include art_misc.h for M_PI, which not necessarily
	is in math.h.

	* Makefile.am: On Win32, build and install import libraries, both
	for gcc and for MSVC (if available).

	* libart-zip.in: New file. Used to build runtime and developer
	package for Win32.

2002-02-06  Laszlo Peter  <[email protected]>

	* configure.in: add AC_FUNC_ALLOCA

	* art_render_gradient.c: copy alloca hacks from glib/galloca.h

2002-02-02  Alexander Larsson  <[email protected]>

	* art_render.c:
	Add special case for art_render_composite_8 for two cases
	that are very common when rendering SVGs with librsvg.
	I'm sure these can be optimized further, but i'm feeling
	very slow today.

2002-02-01  Alex Larsson  <[email protected]>

	* art_render_gradient.c:
	Add optimized case for depth==8,  n_channels == 3

	* test_gradient.c:
	Test case for gradients. Uses gtk+, so not built by
	default.

2002-01-10  Anders Carlsson  <[email protected]>

	* Release 2.3.8

2002-01-04  Anders Carlsson  <[email protected]>

	included first, to test that each header includes what it
	needs.

2002-01-02  Darin Adler  <[email protected]>

	* art_alphagamma.h:
	* art_gray_svp.h:
	* art_pixbuf.h:
	* art_render.h:
	* art_rgb.h:
	* art_rgba.h:
	Add some missing includes.

2001-12-26  Raph Levien  <[email protected]>

	* art_svp_intersect.c: More fixes to intersector. When tops
	coincide, full ordering test is performed (with breaking),
	rather than just comparing b from line eq. Also, had a test
	for x >= backwards in art_svp_intersect_add_point. Thanks
	to Bruce Q. Hammond for test cases.

2001-11-21  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_intersect_break): Changed break
	logic systematically so that new breaks are always in order,
	rather than allowing them to become out of order, then try to fix
	them up later. It's no doubt possible to come up with cases in
	which this reduces precision, but it simplifies life nicely, so I
	did it.
	
	* (art_svp_intersect_horiz): Initialize (a, b, c) values of hs to
	avoid UMR's when they are tested later.

	* art_svp_ops.c (print_ps_vpath): Changed the coordinate
	transform so that it's done in the PostScript rather than
	the C code that outputs the coordinates. This makes it easier
	to reconstruct the vector path from the debug output.

2001-11-16  Alex Larsson  <[email protected]>

	* art_rect.c (art_drect_svp_union, art_drect_svp):
	Don't call art_drect_union() in these functions, since
	it considers zero-width or zero-height svg segments to
	be empty. This causes it to think i.e. rectangular svps
	are empty.

2001-11-07  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_intersect_horiz): Fixed important
	logic bug, failing to test crossings of neighbors when inserting
	horizontal lines. Also changed printf to art_dprint.

	* art_misc.c (art_dprint): Added function for debug printing,
	so verbose intersector output doesn't have to go through printf.

	* art_misc.h (ART_USE_NEW_INTERSECTOR): I've turned this on
	now, as the new intersector certainly seems to be performing
	better than the old one now.

2001-10-31  Anders Carlsson  <[email protected]>

	* Release 2.3.7

2001-10-15  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_intersect_horiz): Minor
	logic fix so that horiz segments successfully cross
	zero length segments in the active list.

	(art_svp_intersect_test_cross): Flags indicating whether to
	do add_point (potentially breaking neighbors) to left and
	to right.

	(art_svp_intersect_insert_cross): Provide ART_BREAK_LEFT and
	ART_BREAK_RIGHT flags to art_svp_intersect_test_cross,
	depending on direction of search.

	(art_svp_intersect_advance_cursor): Provide flags (allow
	both left and right breaking) to test_cross.
	
2001-10-15  Raph Levien  <[email protected]>

	* art_svp_intersect.c (CHEAP_SANITYCHECK): Added an inexpensive
	sanitycheck to detect multiple insertions of a segment into the
	horiz list.

	(art_svp_writer_rewind_add_point): Avoid breaking lines below
	their bottom point.

	(art_svp_intersect_test_cross): Handle cases correctly where
	intersection point matches y0 of left or right segment. These _do_
	happen in real world examples. Also, do add_point on newly
	inserted intersection point.

2001-10-14  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_intersect_add_point): Fixed
	rather subtle logic bug that misplaced insertion point
	when seg argument was NULL.

2001-10-11  Raph Levien  <[email protected]>

	* art_svp_render_aa.c (art_svp_render_aa_iter_step): Got rid
	of qsort of steps, and now keep the step list in sorted order.
	Further, we combine duplicate steps with the same x value,
	which bounds the size of the step list to x1 - x0, so we
	don't need to dynamically resize it. Thanks greatly to
	Bruce Q. Hammond for the original version of this patch.

2001-10-09  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_intersect_test_cross): Breaks
	bottom part of line segments in "too close" cases.

2001-10-09  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_writer_rewind_add_point): Fixed
	bbox computation.
	(art_svp_intersector): Handle degenerate case where input
	SVP has 0 segments.

	* art_svp_intersect.h: Moved definition of art_svp_intersector
	inside #ifdef __cplusplus, so it links properly against C++

2001-10-09  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_intersect_break): Handle
	case when break y equals sweep line correctly. Also adds
	first try at winding number sanitychecker, but that makes
	too many false positives.

2001-10-07  Raph Levien  <[email protected]>

	* art_svp.c (EPSILON): Set to zero if new intersector is
	in use - we want svp's to be in strict sorted order.

	* art_svp_intersect.c (art_svp_intersect_test_cross): Explicitly
	check that top points are equal, and swap immediately if b is out
	of order.
	(art_svp_intersect_horiz): Break segments that intersect
	horizontal lines. Now passes "two squares with offset" test.

2001-10-05  Raph Levien  <[email protected]>

	* art_svp_intersect.c: Major changes to accommodate
	horizontal lines. Intersections of horizontal lines
	aren't fully processed, but should work a lot better
	than before.

	* testart.c: Minor tweaks. testpat now frees memory
	so it can be run under memprof to detect leaks.

2001-10-03  Raph Levien  <[email protected]>

	* art_svp_intersect.c (art_svp_intersect_advance_cursor):
	Made test_cross for inserted segments common between
	intersection processing and cursor advance, and also took
	care of a case that hadn't been handled before. Also added
	invariant sanitychecker for debugging purposes.

2001-10-02  Raph Levien  <[email protected]>

	* art_svp_ops.c: ART_USE_NEW_INTERSECTOR variants of svp
	ops changed to do shallow free of merged svp.

2001-10-01  Raph Levien  <[email protected]>

	* art_svp_intersect.c:
	* art_svp_intersect.h:
	* Makefile.am:
	* art_misc.h:
	* art_svp_wind.h: First commit of new intersector code. It is
	  turned off by default, but can be enabled by #defining
	  ART_USE_NEW_INTERSECTOR in art_misc.h.

	* art_svp_ops.c: Make svp ops use new intersector if enabled.

	* art_svp_vpath_stroke.c: Make vpath stroking use new intersector
	if enabled.
	
	* testart.c: New test case for intersector.

Wed Sep 26 03:48:13 2001  George Lebl <[email protected]>

	* Release 2.3.6

Wed Sep 26 03:11:40 2001  George Lebl <[email protected]>

	* gen_art_config.c: Fix 64bit issues, cast sizeof return when
	  using %d to print it.

2001-09-13  Havoc Pennington  <[email protected]>

	* Makefile.am: rename library to libart_lgpl_2

	* libart-2.0.pc.in (Cflags): move includes

	* libart-config.in: move includes

	* Makefile.am: delete libartConf.sh, rename libart-config
	(EXTRA_DIST): don't install m4 files
	(libart_lgplincdir): move headers

2001-08-03  Michael Meeks  <[email protected]>

	* Version 2.3.5 for the API freeze.

2001-07-12  Darin Adler  <[email protected]>

	* art_affine.c: (art_affine_expansion): Fix handling of
	negative numbers. We ran into this bug a while back when
	figuring out why librsvg couldn't handle certain svg files.

2001-07-12  Darin Adler  <[email protected]>

	* art_misc.h: Change art_expand macro so it's a single
	statement, using the do while (0) trick, which gets rid
	of some warnings.
	* art_pixbuf.c: Add a missing include.
	* art_vpath_svp.c: (art_vpath_from_svp): Initialize a
	variable to avoid a compiler warning.
	* gen_art_config.c: Add a missing include.

2001-03-24  Martin Baulig  <[email protected]>

	Applied the patch from Alexander Larsson which was sitting
	in gnome-libs/patches/libart.diff since February.
	[FIXME: Alex, can you please provide a ChangeLog?])

	* art_rgb_a_affine.[ch]: New files.

2001-01-07  Hans Breuer <[email protected]>
	* art_misc.c : embryonic change to use libart_lgpl on win32
	* libart.def : new file, exported functions for win32 dll
	* makefile.msc : handwritten for MSVC compiler

2000-09-30  Martin Baulig  <[email protected]>

	* libart-2.0.pc.in: Provide pkg-config script.

	* configure.in: Create libart-2.0.pc from libart-2.0.pc.in.
	* Makefile.am (pkgconfig_DATA): Install the libart-2.0.pc
	script in `$(libdir)/pkgconfig'.

2000-08-15  Raph Levien  <[email protected]>

	* art_render.c (art_render_image_solid_negotiate): Only
	sets ART_IMAGE_SOURCE_CAN_COMPOSITE when a compositing
	callback is selected. Previously was causing segfaults on
	non-alpha images. Thanks to Leonard Rosenthol for spotting
	the bug.

Fri Jun 30 22:56:58 2000  Raph Levien  <[email protected]>

	* art_render.c (art_render_composite): Fixed a bug that caused
	it to ignore the alpha setting. Also art_render_composite_8().

2000-06-01  John Sullivan  <[email protected]>

	* art_svp_render_aa.c: (art_svp_render_aa_iter_step):
	Made it build by correcting struct member name from
	Raph's previous checkin.

Wed May 31 11:10:58 2000  Raph Levien  <[email protected]>

	* art_svp_render_aa.c (art_svp_render_aa_iter_step): Updated
	n_steps_max in iter structure after steps reallocation.

Tue May 30 10:33:13 2000  Raph Levien  <[email protected]>

	* art_svp_render_aa.c (art_svp_render_aa_iter_step): Fixed not
	updating iter->steps when steps gets reallocated.

2000-05-30  Pavel Cisler <[email protected]>

	* art_rgba.c:
	Make it build -- fix a broken include.

Tue May 30 00:09:21 2000  Raph Levien  <[email protected]>

	* art_render_gradient.c (art_render_gradient_setpix): Fixed
	an off-by-one loop error.

Mon May 29 15:00:39 2000  Raph Levien  <[email protected]>

	* Makefile.am: Moved relevant .h files into HEADERS stanza.

Mon May 29 13:48:49 2000  Raph Levien  <[email protected]>

	This is a fairly major commit, as it adds both the new, modular
	rendering architecture and gradients. Quite a bit of the code
	feels like "reference code" now, in that it is (hopefully)
	correct, but not necessarily very fast. In addition, there remain
	a few things not done, including the use of SVP's as non-driver
	mask sources. AlphaGamma and filter level also remain
	unimplemented. No compositing modes other than ART_NORMAL are
	implemented. All in good time!
	
	* configure.in: added -Wmissing-prototypes flag. Bumped version
	number to 2.3.0.

	* art_render.h:
	* art_render.c: Added new rendering architecture.

	* art_render_svp.h:
	* art_render_svp.c: Added renderers to use SVP's as mask
	sources in new rendering architecture.

	* art_render_gradient.h:
	* art_render_gradient.c: Added linear and radial gradients
	as image sources in new rendering architecture.

	* art_rgba.h:
	* art_rgba.c: Added functions for manipulating and compositing
	RGBA pixels.

	* art_svp_wind.c: Added static to trap_epsilon(), #ifdef'd out
	traverse().

	* art_uta_ops.c: Added #include "art_uta_ops.h".

	* art_uta_rect.c: Added #include "art_uta_rect.h".

	* art_uta_svp.h: fixed __ART_UTA_SVP_H__ name.

	* art_misc.h: Added ART_GNUC_NORETURN attribute, added that
	to the prototype for art_die(). Added "static" to function
	declarations to avoid warnings when compiled with

	* testart.c: Added gradient test.

Thu May 25 23:30:39 2000  Raph Levien  <[email protected]>

	* art_svp_render_aa.h:
	* art_svp_render_aa.c: Added art_svp_render_aa_iter functions,
	suitable for iterative rendering of an svp, one scan line at a
	time.

	* configure.in: Bumped version to 2.2.0.

Tue May 16 15:03:35 2000  Raph Levien  <[email protected]>

	* art_rgb_pixbuf_affine.c: Included corresponding .h file.

	* art_rgb_pixbuf_affine.h: Put recursive #includes inside
	LIBART_COMPILATION test.

	* art_gray_svp.c:
	* art_rgb_svp.c: Explicit casts for callback data. Also removed
	"render the steps into tmpbuf" comment.

	* gen_art_config.c:
	* Makefile.am:
	* configure.in: Added code to automatically generate an
	art_config.h file, to be installed in libart's include dir. This
	file defines ART_SIZEOF_{CHAR,SHORT,INT,LONG} and art_u{8,16,32}.

	* art_misc.h: Moved definition of art_u8 and art_u32 into
	art_config.h. Added GCC printf format attributes.

	* art_svp_wind.c (traverse): Fixed UMR bug here. The function
	isn't actually used, so it's just for cleanliness.

2000-04-18  Lauris Kaplinski  <[email protected]>

	* art_affine.c (art_affine_to_string): Replaced snprinf with
	art_ftoa to avoid localisation of generated numbers

2000-04-18  ERDI Gergo  <[email protected]>

	* art_rgb_pixbuf_affine.h: Included the ArtPixBuf declaration

Fri Apr 14 16:33:55 2000  Raph Levien  <[email protected]>

	* art_svp_wind.c (art_svp_uncross, art_svp_rewind_uncrossed):
	Fixed uninitialized memory reads when inserting new segment into
	active_segs.

	* art_bpath.c (art_bpath_affine_transform): Made it avoid
	potential uninitialized memory reads when not all the coordinates
	are needed. Thanks to Morten Welinder for spotting both of these
	problems.

2000-04-05  Raph Levien  <[email protected]>

	* art_svp_wind.c: Make "colinear" warnings go to stderr instead
	of stdout. Of course, when I finish the new intersector, these
	will go away entirely.

2000-04-04  Raph Levien  <[email protected]>

	* art_uta_vpath.c (art_uta_add_line): Fixed bug that was causing
	segfaults on alphas. Thanks to msw for localizing it.

2000-01-17  Raph Levien  <[email protected]>

	* art_svp_vpath_stroke.c (art_svp_vpath_stroke): Typo in api
	header (thanks rak).

2000-01-16  Timur Bakeyev  <[email protected]>

	* autoconf.sh: Instead of jumping between srdir and builddir just process
	all the auto* staff in srcdir. In fact, just saying the same things in 
	other words.

2000-01-10  Elliot Lee  <[email protected]>

	* Makefile.am, *.h: Add rather bad hacks to the header files to allow compilation

	* Makefile.am: Distribute libart-config.in

2000-01-09  Raph Levien  <[email protected]>

	art_rgb_pixbuf_affine.c, art_rgb_rgba_affine.c, art_rgb_svp.c,
	art_svp.c, art_svp_ops.c, art_svp_point.c, art_svp_render_aa.c,
	art_svp_vpath.c, art_svp_vpath_stroke.c, art_svp_wind.c,
	art_uta.c, art_uta_ops.c, art_uta_rect.c, art_uta_svp.c,
	art_uta_vpath.c, art_vpath.c, art_vpath_bpath.c, art_vpath_dash.c,
	art_vpath_svp.c: Added API documentation.

Fri Sep 24 17:53:21 1999  Raph Levien  <[email protected]>

	* art_svp_render_aa.c (art_svp_render_insert_active): Avoid
	reading undefined memory (thanks to Morten Welinder).

1999-09-19  Raph Levien  <[email protected]>

	* art_pixbuf.c (art_pixbuf_duplicate): Added a duplicate function
	at the request of Michael Meeks.

1999-09-11  Raph Levien  <[email protected]>

	* art_affine.c (art_affine_to_string): Tightened the predicate for
	matching rotate-only affines, which was too weak. Thanks to lewing
	for spotting it!

1999-09-01  Raph Levien  <[email protected]>

	* art_affine.c, art_alphagamma.c, art_bpath.c, art_gray_svp.c,
	art_misc.c, art_pixbuf.c, art_rect.c, art_rect_svp.c,
	art_rect_uta.c, art_rgb.c, art_rgb_affine.c,
	art_rgb_bitmap_affine.c: Updates to api doc headers.

1999-08-24  Raph Levien  <[email protected]>

	* art_affine.c, art_alphagamma.c, art_alphagamma.h, art_bpath.c,
	art_bpath.h, art_gray_svp.c, art_misc.c, art_pixbuf.c,
	art_pixbuf.h, art_point.h, art_rect.c, art_rect.h: Added api
	documentation headers.

	* testart.c: Added "dash" test, for testing the vpath_dash
	functions.

	* art_rgb_pixbuf_affine.h: Fixed the #ifdef for conditional
	inclusion. Thanks to Kristian Hogsberg Kristensen for spotting
	the bug.

1999-08-24  Raph Levien  <[email protected]>

	* art_svp_render_aa.c (art_svp_render_aa): Added some tests to
	avoid NaN for infinite slopes, which were causing problems on
	Alphas. Closes bug #1966.

1999-08-20  Federico Mena Quintero  <[email protected]>

	* configure.in: Fixed library's libtool version number.

1999-08-03  Larry Ewing  <[email protected]>

	* art_vpath_dash.c (art_vpath_dash): fix a bug/typo that was causing
	certain paths to loop infinitely.

1999-07-28  Raph Levien  <[email protected]>

	* art_vpath_dash.[ch]: Added a function to add a dash style
	to vpaths. It is tested, but has a couple of rough edges (see
	code for details).

	* testart.c: added tests for the new vpath_dash functionality.

	* Makefile.am: added art_vpath_dash.[ch] files.

1999-07-26  Raph Levien  <[email protected]>

	* art_rgb.c (art_rgb_fill_run): fixed incorrect test for
	big-endianness. Thanks to Michael Zucchi for spotting it.

Fri Jul 16 23:42:59 1999  Tim Janik  <[email protected]>

	* art_affine.c (art_affine_flip): flip translation matrixes as well, by
	inverting matrix[4] if (horz) and inverting matrix[5] if (vert).

Fri Jul 16 23:03:26 1999  Tim Janik  <[email protected]>

	* art_pixbuf.[hc]: deprecated art_pixbuf_free_shallow(), people should
	always free pixbufs with art_pixbuf_free() and use the _dnotify variants
	for specific destruction behaviour.
	added art_pixbuf_new_rgb_dnotify() and art_pixbuf_new_rgba_dnotify()
	which allow for a destruction notification function. (this involved
	adding two extra pointers to the ArtPixBuf structure, and removal of
	the recently introduced int flags field).

Mon Jul 12 01:13:23 1999  Tim Janik  <[email protected]>

	* art_affine.[hc]: added art_affine_equal(), which checks two
	matrixes for equality within grid alignment.

Fri Jul  9 17:50:19 1999  Tim Janik  <[email protected]>

	* art_affine.[hc]: added art_affine_flip() to flip a matrix horizontally
	and/or vertically, or just copy it.
	added art_affine_shear() to setup a shearing matrix.

Tue Jul  6 19:03:39 1999  Tim Janik  <[email protected]>

	* art_pixbuf.h: added an int flags; member to the end of the
	structure, it currently only holds information about whether the
	pixels member should be freed. (raph: i think flags is more generic
	than free_pixels, so we can reuse that field if further demands popup
	in the future).

	* art_pixbuf.c:
	(art_pixbuf_new_const_rgba):
	(art_pixbuf_new_const_rgb): new functions that prevent the pixels
	member from being freed upon art_pixbuf_free ().
	(art_pixbuf_free): only free the pixels member if it is non-NULL and
	the PIXBUF_FLAG_DESTROY_PIXELS is set.

1999-07-02  Raph Levien  <[email protected]>

	* art_vpath_bpath.c (art_vpath_render_bez): Bad bad uninitialized
	variables.

	* configure.in: added compile warnings. Guess why :)

1999-06-28  Raph Levien  <[email protected]>

	* art_svp_point.h:
	* art_svp_point.c: Added methods for insideness and distance
	testing, very useful for ::point methods in canvas items.

	* testart.c: test code to exercise the art_svp_point functions.

	* Makefile.am: Additional entries for art_svp_point.

1999-06-28  Raph Levien  <[email protected]>

	* art_svp_render_aa.c (art_svp_render_aa): Subtle boundary
	case in realloc code -- was causing nasty segfaults.

Wed Jun 23 15:05:43 1999  Raph Levien  <[email protected]>

	* art_rgb_svp.c (art_rgb_svp_alpha_opaque_callback): Missed a
	case in the anti-segfault crusade. Thanks lewing!

Wed Jun 23 11:16:42 1999  Raph Levien  <[email protected]>

	* art_rgb_svp.c: Made these routines so they won't segfault even
	if alpha is out of range. Of course, that begs the question of
	fixing the render routines so they won't _make_ alpha go out of
	range, but all in good time.

Fri Jun 18 17:32:34 1999  Raph Levien  <[email protected]>

	* art_vpath_bpath.c (art_bez_path_to_vec): Switched to a new
	adaptive subdivision algorithm, which (finally!) takes flatness
	into account. This should result in both smoother curves and
	faster operation.

Sun Jun 13 21:07:20 1999  Raph Levien  <[email protected]>

	* art_svp_wind.c (art_svp_rewind_uncrossed): Made the winding
	rule logic even more correct :). I somehow missed the fact that
	a clockwise path should be given a winding number of zero;
	last night's commit tried to make it -1 (which worked for the
	test cases I was using).

Sun Jun 13 01:23:14 1999  Raph Levien  <[email protected]>

	* art_svp_wind.c (art_svp_rewind_uncrossed): Change to winding
	rule logic so that it correctly handles the case where the
	leftmost segment is negative.

	* Makefile.am (libart_lgplinc_HEADERS): made art_svp_wind.h
	a public headerfile. This is needed for the bpath canvas item.
	I'm not sure this is the correct way to do it, but it will do
	for now.

	* art_vpath_bpath.h: 
	* art_vpath_bpath.c (art_bez_path_to_vec): Added const to arg.

	* art_vpath_bpath.h: Embarrassing typo.

	* art_bpath.h: Minor tweaks to the #include paths. It is now
	consistent with the other header files.

Wed Jun  9 20:24:45 1999  Raph Levien  <[email protected]>

	* art_svp_vpath_stroke.c: Added all remaining line join and cap
	types, including round, which takes flatness into account. Several
	new internal functions (art_svp_vpath_stroke_arc) and added
	flatness argument to a few internal functions. I might want to
	change the BEVEL join type to MITER for very small turn angles
	(i.e. within a flatness threshold) for efficiency.

	* art_misc.h: Added M_SQRT2 constant.

Wed Jun  2 21:56:30 1999  Raph Levien  <[email protected]>

	* art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): Made the
	closed path detection capable of PostScript semantics (i.e. it
	now senses the difference between ART_MOVETO and ART_MOVETO_OPEN).

	* art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): it now
	filters out successive points that are (nearly) coincident. This
	fixes some of the crashes and hangs, including Tim Janik's
	singularity (trying to stroke MOVETO 50, 50; LINETO 50, 50; END).

	* art_svp_wind.c (art_svp_rewind_uncrossed): added a test to
	correctly handle empty input svp's.

	* art_svp_wind.c (art_svp_uncross): added a test to correctly
	handle empty input svp's.

Sun Jan 17 20:53:40 1999  Jeff Garzik  <[email protected]>

	* art_affine.c:
	Include string.h for memcpy.

	* art_svp_vpath.c:
	Remove conflicting static func definition.

	* art_uta_svp.c:
	Include art_vpath_svp.h for func definition.

Mon Jan  4 12:47:47 1999  Raph Levien  <[email protected]>

	* art_bpath.c (art_bpath_affine_transform): Stupid misnaming
	of this function (forgot the "art_").

Thu Dec 31 09:04:23 1998  Raph Levien  <[email protected]>

	* art_affine.c (art_affine_rectilinear): Added this function.

	* art_rect.c (art_drect_affine_transform): Corrected the name (it
	was right in the .h). Also made it work with non-rectilinear
	transforms, while I was at it.

Thu Dec 17 11:58:24 1998  Raph Levien  <[email protected]>

	* art_alphagamma.h:
	* art_alphagamma.c: The real code for alphagamma.

Wed Dec 16 14:18:46 1998  Raph Levien  <[email protected]>

	* art_alphagamma.h:
	* art_alphagamma.c: Added. At present, it only contains a dummy
	stub. When the real code is added, it supports doing alpha
	compositing in a gamma-corrected color space (suppressing
	jaggies).

	* art_pixbuf.h:
	* art_pixbuf.c: Added. This is a virtualization layer over
	a few different kinds of image formats.

	* art_rgb_pixbuf_affine.h:
	* art_rgb_pixbuf_affine.c: Added. Supports compositing of
	generic images over an rgb buffer.

	* art_affine.h: 
	* art_affine.c (art_affine_expansion): Added this function,
	which reports the exact scale factor in the case of rotation,
	scaling, and transformation (an approximate number in the
	case of shearing or anamorphic distortion).

	* art_misc.h:
	* art_misc.c (art_warn): Added.

	* art_rgb_affine.h:
	* art_rgb_affine.c: Added alphagamma argument (not yet implemented).

	* art_rgb_affine_private.c: Fixed typo bug that was causing
	repaint problems for nonsquare images.

	* art_rgb_bitmap_affine.h:
	* art_rgb_bitmap_affine.c: Major speed improvement, probably fixed
	correctness while I was at it. Added alphagamma argument (not yet
	implemented).

	* art_rgb_svp.h:
	* art_rgb_svp.c: Added alphagamma argument (only implemented
	in aa case, not yet alpha case).

	* art_vpath.c: increased perturbation to 2e-3, because the old
	value (1e-6) was too small.

	* testart.c: added alphagamma.
	
	* Makefile.am: added new files

Sun Dec 27 21:45:03 1998  Raph Levien  <[email protected]>

	* art_rect.h: 
	* art_rect.c: Added DRect versions of the basic ops (double
	rather than int).

	* art_rect_svp.h:
	* art_rect_svp.c: Added. This computes the bounding box of
	an svp.

Wed Dec 16 14:18:46 1998  Raph Levien  <[email protected]>

	* art_alphagamma.h:
	* art_alphagamma.c: Added. At present, it only contains a dummy
	stub. When the real code is added, it supports doing alpha
	compositing in a gamma-corrected color space (suppressing
	jaggies).

	* art_pixbuf.h:
	* art_pixbuf.c: Added. This is a virtualization layer over
	a few different kinds of image formats.

	* art_rgb_pixbuf_affine.h:
	* art_rgb_pixbuf_affine.c: Added. Supports compositing of
	generic images over an rgb buffer.

	* art_affine.h: 
	* art_affine.c (art_affine_expansion): Added this function,
	which reports the exact scale factor in the case of rotation,
	scaling, and transformation (an approximate number in the
	case of shearing or anamorphic distortion).

	* art_misc.h:
	* art_misc.c (art_warn): Added.

	* art_rgb_affine.h:
	* art_rgb_affine.c: Added alphagamma argument (not yet implemented).

	* art_rgb_affine_private.c: Fixed typo bug that was causing
	repaint problems for nonsquare images.

	* art_rgb_bitmap_affine.h:
	* art_rgb_bitmap_affine.c: Major speed improvement, probably fixed
	correctness while I was at it. Added alphagamma argument (not yet
	implemented).

	* art_rgb_svp.h:
	* art_rgb_svp.c: Added alphagamma argument (only implemented
	in aa case, not yet alpha case).

	* art_vpath.c: increased perturbation to 2e-3, because the old
	value (1e-6) was too small.

	* testart.c: added alphagamma.
	
	* Makefile.am: added new files

Mon Dec 14 00:16:53 1998  Raph Levien  <[email protected]>

	* art_affine.c (art_affine_to_string): re-added the "scale" method
	that was accidentally deleted before check-in.

	* Makefile.am: added new files

Sun Dec 13 00:52:39 1998  Raph Levien  <[email protected]>

	* art_affine.h:
	* art_affine.c: Added. Everything you ever wanted to do with an
	affine transform. Especially check the functions that generate
	concise PostScript strings for affine transforms.	

	* art_filterlevel.h: A simple enum for selecting filtering
	style.

	* art_rgb_affine.h:
	* art_rgb_affine.c (art_rgb_affine): Added. This function
	composites an (opaque) rgb image over an rgb pixel buffer. At
	present, it's slow and only nearest neighbor filtering is enabled.

	* art_rgb_rgba_affine.h:
	* art_rgb_rgba_affine.c: Analogous, but for compositing rgba
	images.

	* art_rgb_bitmap_affine.h:
	* art_rgb_bitmap_affine.c: Analogous, but for compositing bitmap
	images.

	* art_rgb_affine_private.c (art_rgb_affine_run): Added. This is
	a common function used by all the rgb_affine modules to move
	testing for source image bbox out of the inner loop.

	* Makefile.am: added the new files

	* testart.c: exercise the image compositors

Wed Dec  9 23:36:35 1998  Raph Levien  <[email protected]>

	* art_vpath.c (art_vpath_perturb): Made it deal correctly
	with closed paths (the MOVETO and closing LINETO have to
	agree).

	* art_svp_wind.c: Made the bbox calculations for the resulting
	svp's correct.

	* art_svp.h:
	* art_svp.c: The art_svp_seg_compare function moved here, because
	it's required in art_svp_ops.

	* art_svp.c (art_svp_add_segment): It now does bbox calculations.

	* art_svp_ops.h: 
	* art_svp_ops.c: Added. Populated with basic union, intersection,
	and diff functions.

	* art_vpath_svp.h: 
	* art_vpath_svp.c: Added. Populated with a function to convert
	from sorted to unsorted vector paths

	* Makefile.am: added the new files

	* testart.c: exercise the stroke outline and vector path
	operations.

1998-12-08  Herbert Valerio Riedel  <[email protected]>

	* art_svp_wind.c: added #include <string.h> for memcpy()

Sun Dec  6 22:15:12 1998  Raph Levien  <[email protected]>

	* art_svp_wind.[ch], art_svp_vpath_stroke.[ch]: Added, but it
	doesn't work yet. These will do stroke outline and basic
	vector ops like union, intersect, etc.

	* art_svp_render_aa.c: Added a simple speedup based on bbox
	culling. I will want to do more speedups, but none of this is
	necessary for the freeze.

	* art_svp_vpath.c: Fixed some bugs in the art_svp_from_vpath in
	cases where there is more than one subpath.

	* art_vpath.h:
	* art_vpath.c (art_vpath_perturb): Added this function.  This will
	help cheat as long as the basic vector ops have numerical
	stability problems.

Fri Dec  4 18:00:38 1998  Raph Levien  <[email protected]>

	* art_svp_render_aa.c (art_svp_render_aa): Changed the api
	slightly, to guarantee that the steps are all within the range
	from x0 (inclusive) to x1 (exclusive).

	* art_gray_svp.c, art_gray_svp.h: Added. Populated with functions
	to render into a simple graymap.

	* art_rgb.c, art_rgb.c: Added. Populated with fill_run and
	run_alpha methods.

	* art_rgb_svp.c, art_rgb_svp.h: Added. Populated with functions to
	render into an RGB buffer, and to composite over an RGB buffer.

	* Makefile.am: added art_gray_svp, art_rgb, and art_rgb_svp.

	* testart.c: test the color and layered rendering.

Mon Nov 30 01:30:25 1998  Raph Levien  <[email protected]>

	* testart.c: added vector path rendering stuff. Some of it needs
	to go out of the test framework and into the module, but the
	api hasn't settled down entirely yet (in the real code, all
	x's in the step field are within bounds).

	* art_svp_render_aa.c, art_svp_render_aa.c.h: added.

	* art_svp_vpath.c, art_svp_vpath.h: added.

	* art_pathcode.h: added ART_MOVETO_OPEN (libart uses an
	ART_MOVETO_OPEN code at the beginning to indicate an open path,
	while PostScript uses the lack of a closepath at the end).

	* art_vpath_bpath.c, art_vpath_bpath.h: fixed it up, added
