Changes since the last public release (1.4.0beta107):
version 1.4.1alpha01 [November 27, 2009]
Based on 1.4.0beta107 (prerelease)
version 1.4.1alpha02 [December 11, 2009]
Restored premultiplied alpha feature from version 1.4.0beta105.
Added "double gamma" to parameters for png_set_premultiply_alpha().
Added "float postmultiply_gamma" member to the png_struct.
Moved PNG_DIVIDE_BY_255, PNG_8_BIT_PREMULTIPLY(), etc., from
png.h to pngpriv.h
Updated documentation about png_set_premultiply_alpha().
Always expand pixels to 16-bit samples when premultiplying.
In pngconf.h, require PNG_GAMMA_SUPPORTED to be defined when defining
PNG_READ_PREMULTIPLY_ALPHA_SUPPORTED
Eliminated PNG_DIVIDE_BY_255 and PNG_8_BIT_PREMULTIPLY macros
leaving only PNG_DIVIDE_BY_65535 and PNG_16_BIT_PREMULTIPLY
because we will always work with 16 bits.
Sync with version 1.4.0beta107:
Updated README
Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files.
Removed "-DPNG_CONFIGURE_LIBPNG" from the makefiles, projects, and contrib.
Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco
to put png.h and pngconf.h in $prefix/include, like the other scripts,
instead of in $prefix/include/libpng. Also revised makefile.sco
to put them in $prefix/include/libpng14 instead of in
$prefix/include/libpng/libpng14.
Relocated png_do_chop() to its original position in pngrtran.c; the
change in version 1.2.41beta08 caused transparency to be handled wrong
in some 16-bit datastreams (Yusaku Sugai).
