[AD] Patch for rotate.c

["David A. Capello" <dacap@xxxxxxxxxx>]

This patch fix a ugly error when you rotate a sprite over a
non-clipped bitmap (this patch is for 4.0.3, but should be applied in
all branches).

If you compile the test with the current Allegro version you can see:

  Moving the sprite to the:
  - left side: all work fine
  - right side: some extra pixels appears in the left side
  - top side and bottom side: SEG FAULT

The segmentation fault is correct (because we desactivate the
clipping), but the extra pixels that appears in left side when we
rotate a sprite over the right side, that is bad.
