No changes.
version 1.2.17rc2 [May 9, 2007]
Moved several PNG_HAVE_* macros out of PNG_INTERNAL because applications
calling set_unknown_chunk_location() need them.
Changed transformation flag from PNG_EXPAND_tRNS to PNG_EXPAND in
png_set_expand_gray_1_2_4_to_8().
Added png_ptr->unknown_chunk to hold working unknown chunk data, so it
can be free'ed in case of error. Revised unknown chunk handling in
pngrutil.c and pngpread.c to use this structure.
