skia2/bench/BlurBench.cpp
senorblanco@chromium.org 91f489a65d Modify the blur bench to add tests for high-quality blurs, and large non-integer blurs. Change the Coarse flag (which just turns on separable blurs) to an #ifdef, since separable is no longer just Coarse. (This #ifdef will hopefully be shortlived, once Chrome has switched).
The separable blur algorithm gives +45% on SampleBlur, +84% on SampleBigBlur, +31% on TheVerge, +35 to +85% on blurbench in HQ (depending on size), +8 to +35% in low quality.  (All of these on 32bit MacPro).
