Changes since the last public release (1.2.16):
version 1.2.17beta1 [May 12, 2007]
Revised scripts/CMakeLists.txt to install both shared and static libraries.
Deleted a redundant line from pngset.c.
version 1.2.17beta2 [April 26, 2007]
Relocated misplaced test for png_ptr == NULL in pngpread.c
Use "==" to "&" for testing PNG_RGB_TO_GRAY_ERR & PNG_RGB_TO_GRAY_WARN flags.
Added pngerror() when write_IHDR fails in deflateInit2().
Added "const" to some array declarations.
Mention examples of libpng usage in the libpng*.txt and libpng.3 documents.
version 1.2.17rc1 [May 5, 2007]
No changes.
version 1.2.17rc2 [May 8, 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.
version 1.2.17rc3 [May 8, 2007]
Revised symbol-handling in configure script.
version 1.2.17rc4 [May 12, 2007]
Revised unknown chunk handling to avoid storing unknown critical chunks.
