The attached writepng.c fixes a bug discovered by Hans:

In the new version, Colorspaces were always written direct
(img_colorspace_ref() was ignored). That broke the image color
processing that ConTeXt does.

Bugfixes in 16-bit color depth mode (needs an 8-bit alpha
channel) and corrected PNG transformation discovery for gray
conversion.

This is a final version for now, it should be added to a
pdftex beta to allow 'in the wild' testing.

This new version incorporates the code from Hartmut's speed 
patch.
