This bug has already been fixed:

-art's bitmap rendering should be correct now, at least according to my
DPSTest testing. -xlib won't compile with recent gcc snapshots, so I
haven't tested it, but the code looks ok. Thus, if there are problems,
they're probably caused in NSBitmapImageRep or higher layers.

Backtraces with debug info would be nice. :)
Anyway, Riccardo has given me some example images that can trigger the
odd behavior, so I'm investigating.
