Bug 818025 - Fix BasicTiledThebesLayer fast path. r=bgirard

Browse Source 
When disabling low precision and progressive rendering, BasicTiledThebesLayer
takes a fast path that avoids a lot of region operations, transformation and
iterations. Unfortunately, it also forgets to check if the mask layer exists
before trying to draw it, which causes an immediate crash in most cases.
