Dimitrie O. Paun 318817f723 - Rewrite the drawing code. It now is much smaller, easier to follow, 
and faster. Moreover, it now supports the dwRop operation, and it is
  in good shape to support the missing features.
- Draw the dragged image semi-transparently (will work when we support
  alpha blending).
