Commit Message:
GOB: Make coordinate parameters in Surface::fillRect() signed
And clip to [0, width), [0, height) before drawing.
This fixes bug #6864, which is a regression I introduced in
51fd528fe56e00466255d54e1e71b19f34729bfd when I changed all
the drawing code to use the Surface class.
I thought that having unsigned coordinates makes sense, but
for some reason, Fascination sets _destSpriteX (which maps
to left in fillRect()) to -1, expecting the drawing code to
clip.
