Libpng 1.2.2beta1 - February 22, 2002
This is not intended to be a public release. It will be replaced
within a few weeks by a public version or by another test version.
Changes since the last public release (1.2.1):
version 1.2.2beta1 [February 22, 2002]
Fixed a bug with reading the length of iCCP profiles (Larry Reeves).
Revised makefile.linux, makefile.gcmmx, and makefile.sgi to generate
libpng.a, libpng12.so (not libpng.so.3), and libpng12/png.h (not png.h)
Revised makefile.darwin to remove "-undefined suppress" option.
Added checks for gamma and chromaticity values over 21474.83, which exceed
the limit for PNG unsigned 32-bit integers when encoded.
Revised calls to png_create_read_struct() and png_create_write_struct()
for simpler debugging.
Revised png_zalloc() so zlib handles errors (uses PNG_FLAG_MALLOC_NULL_MEM_OK)
