2TODO - list of things to do for libpng:
3
4Final bug fixes.
5Better C++ wrapper/full C++ implementation?
6Fix problem with C++ and EXTERN "C".
7cHRM transformation.
8Remove setjmp/longjmp usage in favor of returning error codes. As a start on
9  this, minimize the use of png_error(), replacing them with
10  png_warning(); return(0; or similar.
11Palette creation.
12Add "grayscale->palette" transformation and "palette->grayscale" detection.
13Improved dithering.
14Multi-lingual error and warning message support.
15Complete sRGB transformation (presently it simply uses gamma=0.45455).
16Man pages for function calls.
17Better documentation.
18Better filter selection
19   (counting huffman bits/precompression?  filter inertia?  filter costs?).
20Histogram creation.
21Text conversion between different code pages (Latin-1 -> Mac and DOS).
22Avoid building gamma tables whenever possible.
23Use greater precision when changing to linear gamma for compositing against
24  background and doing rgb-to-gray transformation.
25Investigate pre-incremented loop counters and other loop constructions.
26Add interpolated method of handling interlacing.
27Switch to the simpler zlib (zlib/libpng) license if legally possible.
28Extend pngvalid.c to validate more of the libpng transformations.
