we handle witn win32 only basic compositing (only "total transparent") and it does work now. Otherwise, the cairo backend needs to be used.

this is a problem analyzed several times by Fred, but he got no solution yet.

it happens only on windows 2000, not on XP

it happens only on real hardware. People using virtual machines don't see it.
Employing vnc to show the screen to somebody else, installs a virtual screen driver... and magically teh problem is not gone only to the observer, but also on the local screen. So it is very hideous to show it others....

AFAIK, the winlib graphics backend is pretty simple and
doesn't handle compositing. It would be nice if we could get
the art graphics backend working on Windows. I'm not sure
about the image shifting...

1. Transparent areas in tiff images ouccur black. (or
is this a problem in libtiff on win32?)


2. Images are sometimes placed wrong.
