Now that we have geometry shaders, we can leverage this to implement
clears of layered framebuffers by adding a geometry shader in our
clear pipelines that redirects the clear rect to the appropriate
layer in the framebuffer, instead of falling back to emitting separate
clear jobs for each layer, which is a lot slower.
