This is not a complete fix. After spending a few hours with this I do
understand things now better. For certain video cards (i.e. mine ;) such
as the ATI-Mach64 there is a difference between the depth of the
visual and the needed layout of the pixmap-buffer.

In other words, the call to XCreateImage in x11.c respectivly the
return value of wingetdepth() is broken for some hardware and I will
send a patch today evening. If you only get at a reasonable picture with
x11_2.c and a depth of 16bit you do suffer from this problem.

Greetings, Peter
