Resolves: #i118905# Changed EditEngine to be able to paint to overlay directly

i.e. paint to VirtualDevice as well, not only to Window.
Removed the no longer needed switch between buffered and unbuffered overlay,
this removes the flickering white block.

(cherry picked from commit 5ab32faf2426fa60f975d0b544cfd671cdc7983b)
