* DrawingEngine::CopyBits() was invalidating the wrong region (without offset) 

when the HWInterface was using acceleration and at the same time double
  buffering.
* _CopyToFront() should always be used, since it calls a protected virtual that
  derived classes of HWInterface depend on. This fixes some graphics glitches
  in certain situations.
