Visual Studio (Sergey Kosarevsky)
Merged pngwrite.c with libpng-1.6.17beta06/pngwrite.c
Version 1.7.0beta55 [March 7, 2015]
Version 1.7.0beta55 [March 8, 2015]
Removed some comments that the configure script did not handle
properly from scripts/pnglibconf.dfa and pnglibconf.h.prebuilt.
Stopped a potential memory leak in png_set_unknown_chunks(). Breaks
tests/pngunknown-sAPI so it's temporarily marked SKIP.
Spelling fixes ("then", "occured") reported by Lauri Nurmi.
