+Bugs:
+ 0) Just showing the meta info can cause the file to be rewritten!!!
+ 1) utf-8 paths must be tested and supported.
+ 2) Display of EXIF comments need to be tested.
+ Both Unicode & ASCII need testing.
+
+New features needed:
+ 1) Should switch to a multi-line editor for comments. Support "\n".
+ 2) Should autodetect if the jpeg COM is in utf-8 format.
+ 3) Allow editing the EXIF "Orientation" flag (without rewriting the exif header).
+ 4) Extract and return the EXIF thumbnail, oriented properly, as an alternative
+ to the much slower process of generating a new thumbnail.
+
+Future features:
+ 1) Allow the user to erase or move comment in either the EXIF or jpeg COM.
+ 2) Play or return audio files associated with the exif.
