44e26d4149 [devel] Revised commentary about png_set_alpha_mode() to make it clearer 
that this only affects how composited pixels are returned to the calling
application; they don't affect the pixels that are written to a PNG file.

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.

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.

4a12f4a22a [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.
