russ,

i posted a little bit on this.  the problem is these two lines in png.c:

 165 		if(defaultcolor && screen->depth>8 && outchan==CMAP8)
 166 			outchan = RGB24;

if they are commented out (and i think if you replace RGB24 with RGBA32),
the image appears correctly.  using the v flag also works (for the wrong reasons).

the problem is in the conversion from the ABGR rawimage to RGB24.  i hadn't
narrowed down where the problem occurs.
