    (counting huffman bits/precompression?  filter inertia?  filter costs?).
 Histogram creation.
 Text conversion between different code pages (Latin-1 -> Mac and DOS).
-Should we always malloc 2^bit_depth PLTE/tRNS/hIST entries for safety?
 Build gamma tables using fixed point (and do away with floating point entirely).
+Avoid building gamma tables whenever possible.
 Use greater precision when changing to linear gamma for compositing against
   background and doing rgb-to-gray transformation.
 Investigate pre-incremented loop counters and other loop constructions.
 Add interpolated method of handling interlacing.
+Provide for conditional compilation of 16-bit support (except for the
+  initial stripping down to 8-bits when reading a 16-bit PNG datastream).
+Switch to the simpler zlib (zlib/libpng) license if legally possible.
