- Depends on the drawing operation. If you go through the window then
- every drawing operation is clipped to the window. But if you are
- going for a borderless backdrop window and don't need any windows
- on top of it then you can also render to the screens RastPort. The
- screens RastPort is not clipped and you must ensure that you do not
- use coordinates outside the bitmap.
