Fix color problems with overlays (fix #1914)

Browse Source 
There were two problems:
1) Overlays weren't using the screen color space, so restoring the
   pixels were modifying the original saved area
2) A custom cursor (when "Use native cursors" option were enabled) was
   using overlays, when we could use a native custom cursor
   anyway (without overlays)
