Surface damage has a curious relationship with buffer damage. If we change our buffer orientation, the whole buffer contents will likely change. The application is really only supposed to tell us what parts of the surface changed, which could still just be a subset.
Since the gl renderer uses the damage rectangles for texture uploads, it won't upload the entire buffer contents after an orientation change. To deal with this we just damage the entire surface any time the buffer viewport changes. This fixes weston_simple_damage --rotating-transform when using the gl renderer.
