Relative to Unity7 on the Pineview system:
mir_proving_server is much faster than Unity7 (perfect 60FPS compositing
and egltriangle up to 1000FPS).
Unity8 is much slower than Unity7 (only a couple of FPS at most and
sometimes less than 1).
Seems like (similar to mir_demo_client_eglplasma) some advanced shaders
cause the performance to fall off a cliff. It's not obvious where the
edge of the cliff is though, because everything keeps working, just much
slower.
We probably need a shader/GL debugging expert to look into it.
