Fix viewsize not working correctly with the GL renderers.

Browse source 
The GL renderers require that the borders are redrawn after every
glClear() call, the damage tracking doesn't take that into account.
Since the speedup by the damage tracking is neglibiable in the GL
renderers, don't use it. Just redraw everything when we're running
with everthing which isn't the soft renderer.
