version 1.0.55 [July 9, 2011] version 1.0.57 [February 18, 2012]
Fixed uninitialized memory read in png_format_buffer() (Bug Updated contrib/pngminus/makefile.std (Samuli Souminen)

before IDAT.
Ported bugfix in pngrtran.c from 1.5.3: when expanding a paletted image,
always expand to RGBA if transparency is present.
Check for integer overflow in png_set_rgb_to_gray().
Check for sCAL chunk too short.
Added CMakeLists.txt, projects/xcode, and pnggccrd.c to EXTRA_DIST in
Makefile.am and Makefile.in
