Eric Anholt e4d11e58ce Remove the PaintWindow optimization.
This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive.  This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it.  No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
