[devel] Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is
...
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
wrong in 128 out of 65536 cases. Getting the right answer all the time
without division is easy.

[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.

[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.)
