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