I looked in zwgc for all uses of clip rectangles. There is some code
which sets a region to draw in, but it seems to do things correctly
(that is, it uses Xlib calls to set up the region).
Look in X_gram.c.
This code would be wrong if XUnionRectWithRegion did not allow the
input and output region to be the same. It's not immediately obvious
from looking at the Xlib code if this is the case.
