XQuartz: Don't crash if CG increases our display resolution
miPaintWindow would cause fbFill() to overwrite pScreen's pixmap which was
sized for the old resolution.

XQuartz: RandR: Don't crash if X11 is launched while there are no attached displays
If CG reports no displays when launching, we could crash in RandR. Instead, just
provide a fake 800x600 display until we are notified about displays being attached.
