On r200, you have to reset the scissors when you switch to EXA or your
rendering gets clipped.  Also you can only scale the video to a certain size
before it stops rendering.  I suspect we are hitting a coordinate limit
somewhere due to the huge triangle.  All chips support rect lists (not just
r100).  That might be a better solution if it renders then as rects rather than
as triangles.
