[devel] Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again.
...
If this is not enabled, png_set_strip_16() and png_do_scale_16_to_8()
aren't built.

png_snprintf.

[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().

[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!

[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.

[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.

[devel] Cleanup of conditional compilation code and of background/gamma
...
handling. Internal changes only except for a new option to avoid compiling
in the png_build_grayscale_palette API (which is not used at all internally.)
The main change is to move the transform tests (READ_TRANSFORMS,
WRITE_TRANSFORMS) up one level to the caller of the APIs.
