REVISION SUMMARY
  On Wayland per output rendering is performed and paintScreen is invoked
  for every output. Some effects need the information which output is
  currently being rendered as otherwise e.g. FBO access could fail.
  
  This change adds the current output geometry to ScreenPaintData. On X11
  (all outputs one geometry) this information is not set and a null rect
  is returned. That way the effects can also easily check which rendering
  mode is used.
