* fixed the dirty canvas when Icon-O-Matic is started in Haiku

(and also improved performance of rendering icons, the background
  was cleared for no reason on each Draw() call) However there
  must be a bug still in the app_server which causes GetClippingRegion()
  to return an out-of-date clipping region (R5 has the very same bug
  though)
