f3f7e14727 [libpng15] Fixed 64-bit compilation errors (gcc). The errors fixed relate 
to conditions where types that are 32 bits in the GCC 32-bit
world (uLong and png_size_t) become 64 bits in the 64-bit
world.  This produces potential truncation errors which the
compiler correctly flags.

550bab03fb [devel] Removed the ACCURATE and LEGACY options (they are no longer useable) 
Fixed some compiliation problems with scaling options.

b2bee3374c [devel] Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is 
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
    wrong in 128 out of 65536 cases. Getting the right answer all the time
    without division is easy.

d273ad2d0f [devel] Implementation of premultiplied alpha support: png_set_alpha_mode 
(libpng-manual.txt still to be updated, see png.h for documentation.)

c5bef946b1 [devel] IDAT compression failed if preceded by a compressed text chunk 
This was because the attempt to reset the zlib stream in png_write_IDAT
happened after the first IDAT chunk had been deflated - much too late.
In this change internal functions are added to claim/release the z_stream
and, hopefully, make the code more robust.  Also deflateEnd checking is
added - previously libpng would ignore an error at the end of the stream.

c559bb58ed [devel] Added PNG_WRITE_OPTIMIZE_CMF_SUPPORTED macro to make zlib "CMF" 
optimization configureable.

88b77cc6f3 [devel] Remove png_snprintf, add formatted warning messages. 
This change adds internal APIs to allow png_warning messages to have parameters
 without requiring the host OS to implelment snprintf.  As a side effect the
 dependency of the RFC1132 code on stdio is removed and PNG_NO_WARNINGS does
 actually work now.

c683100e31 [devel] zlib text compression parameters fall back on non-IDAT parameters
