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.
- Fix launch of X clients by double clicking in the Finder when there is a
space in the path (Torrey T. Lyons).
- Interpret scroll wheel mouse events correctly when shift is held down
(Benjamin Burke).
- Add option to always use Mac command key equivalents (John Harper and
Torrey T. Lyons).
- Add support for dynamic screen configuration changes in rootless mode
(John Harper and Torrey T. Lyons).
- Add documentation on generic rootless layer (Torrey T. Lyons).
