-Improve API by hiding the info_ptr.
+Avoid building gamma tables whenever possible.
+Use greater precision when changing to linear gamma for compositing against

+Investigate pre-incremented loop counters and other loop constructions.
+Add interpolated method of handling interlacing.
+Switch to the simpler zlib (zlib/libpng) license if legally possible.
+Extend pngvalid.c to validate more of the libpng transformations.
