clutter/cogl/stage: Use fb size for for fallback fb clip region

Browse Source 
When calculating the fallback framebuffer clip region, which should be
the region in framebuffer coordinates, we didn't scale the view layout
with the view framebuffer scale, meaning for any other scale than 1,
we'd draw a too small region of the view. Fix this by just using the
size of the framebuffer directly, avoiding any scale dependent
calculation all together.
