+TODO list for libpng
+--------------------
 
-* Fix all defects (duh!)
-* Better C++ wrapper / full C++ implementation (?)
-* Fix the problems with C++ and 'extern "C"'.
-* cHRM transformation.
-* Palette creation.
-* "grayscale->palette" transformation and "palette->grayscale" detection.
-* Improved dithering.
-* Multi-lingual error and warning message support.
-* Complete sRGB transformation.  (Currently it simply uses gamma=0.45455.)
-* Man pages for function calls.
-* Better documentation.
-* Better filter selection
-  (e.g., counting huffman bits/precompression; filter inertia; filter costs).
-* Histogram creation.
-* Text conversion between different code pages (e.g., Latin-1 -> Mac).
-* Avoid building gamma tables whenever possible.
-* Greater precision in changing to linear gamma for compositing against
-  background, and in doing rgb-to-gray transformations.
-* Investigate pre-incremented loop counters and other loop constructions.
-* Interpolated method of handling interlacing.
-* More validations for libpng transformations.
