It's a tiny bit complicated.

     Note that passing "out-of-bitmap" coordinates is allowed, but they are
     likely to be altered (and so the coordinates returned by get_clip_rect()
     would return be different). However, such modifications are guaranteed to
     preserve the external effect of the clipping rectangle, that is not to
     modify the actual area of the image that it is ok to draw onto.
