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

optimization configureable.

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.

0a5c9c02fa [devel] Corrected const_png_ in png.h to png_const_ to avoid polluting 
the namespace.  Added png_get_current_row_number and
 png_get_current_pass_number for the
 benefit of the user transform callback.
 Added png_process_data_pause and png_process_data_skip for the benefit of
 progressive readers that need to stop data processing or want to optimize
 skipping of unread data (e.g. if the reader marks a chunk to be skipped.)

4f108d8af6 [devel] Supply default values for PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX 
in pngpriv.h in case the user forgot to define them in their pngusr.h.  This
means it is safe for people not building a DLL to omit these defines from pngusr.h.
