AW: We identified all places where changes take place, but there are two 
problems: 
(a) Not all that calls are inside paint()
(b) More than one pair of begin/end paint is used

BeginDrawLayers/EndDrawLayers is desinged for the standard repaint to be called
once each at begin and end of paint. Calling multiple times will lead to
problems since BeginDrawLayers contains functionality to update Drawinglayer
hierarchy and to calculate a ClipRegion especially for Paint()-ClipRegion of a
Window.
So, BeginDrawLayers/EndDrawLayers needs to be called ONLY in Paint() and changes
outside paint() will need a 2nd mechanism to provide the changes to
OverlayManager of DrawingLayer. Hmmm...
