Greg Daniel 5d67b1797a [graphite] Use finished callbacks in nanobench to manage frames.
In nanobench we want to try and simulate a GPUs swapbuffering and not
get too far ahead on the CPU. Thus we use finished callbacks to know if
we get more than 3 frames ahead of the GPU. This CL adds support for
Graphite to do this.
