Changes since the last public release (1.5.0):
version 1.5.1beta01 [January 8, 2011]
Added description of png_set_crc_action() to the manual.
Added a note in the manual that the type of the iCCP profile was changed
from png_charpp to png_bytepp in png_get_iCCP(). This change happened
in version 1.5.0beta36 but is not noted in the CHANGES. Similarly,
it was changed from png_charpp to png_const_bytepp in png_set_iCCP().
Ensure that png_rgb_to_gray ignores palette mapped images,
Fixed the failure to handle palette mapped images correctly.
Version 1.5.1beta02 [January 14, 2011]
Fixed a bug in handling of interlaced images (bero at arklinux.org).
Updated CMakeLists.txt (Clifford Yapp)
Version 1.5.1beta03 [January 14, 2011]
Fixed typecasting of some png_debug() statements (Cosmin)
Version 1.5.1beta04 [January 16, 2011]
Updated documentation of png_set|get_tRNS() (Thomas Klausner).
Mentioned in the documentation that applications must #include "zlib.h"
if they need access to anything in zlib.h, and that a number of
macros such as png_memset() are no longer accessible by applications.
Corrected pngvalid gamma test "sample" function to access all of the color
samples of each pixel, instead of sampling the red channel three times.
