Used wxRegion code from wxX11.

Browse Source 
Removed update rect list from wxWindow
(not necessary anymore).
  Simplified and corrected clipping region handling
in wxWindowDC. Stopped wxWindowDC::DoBlit from
destroying the clipping region.
  Simplified wxPaintDC code.
Added wxWindow::DoCreateScrollBar helper function.
