1921e6db90 [devel] Reversed earlier change of transformation order; move 
png_expand_16 back where it was before libpng-1.5.3beta07.
The change doesn't work because it requires 16 bit gamma tables when the code
only generates 8 bit ones.  This fails silently; the libpng code just doesn't
do any gamma correction.  Moving the tests back leaves the old, inaccurate, 8
bit gamma calculations, but these are clearly better than none!

cb0b29631f [devel] Documented png_set_alpha_mode(), other changes in libpng.3 and 
libpng-manual.txt.
  The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative
    parameters are supplied by the caller), while in the absence of cHRM
    sRGB/Rec 709 values are still used.
  The bKGD chunk no longer overwrites the background value set by
    png_set_background(), allowing the latter to be used before the file
    header is read. It never performed any useful function to override
    the default anyway.

2d3fc1ca3b [devel] Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and 
PNG_AFTER_IDAT from pngpriv.h to png.h because they must be visible to
applications that call png_set_unknown_chunks().

f70c7d02e9 [devel] Added named value and 'flag' gamma support to png_set_gamma. Made a 
minor change from the previous (unreleased) ABI/API to hide the exact value
used for Macs - it's not a good idea to embed this in the ABI!

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.

 skipping of unread data (e.g. if the reader marks a chunk to be skipped.)
