senorblanco@chromium.org 3f2d45aff6 (Relanding r7275 with assert fix, plus fixes from r7276, r7280, r7283.) 
Implement a bicubic resampling image filter, with raster and GPU backends.
In order to get this to work on the GPU side, I had to modify the width and height of the drawn texture in drawSprite() and drawDevice() to use the filtered texture's dimensions, instead of the source texture.  (This wasn't a problem before since all other image filters produce results the same dimensions as their input texture.)
For now, this implementation only does axis-aligned scaling (same as the Lanczos-3 implementation in Chrome).  It's also done for correctness and clarity, not speed, so there are lots of opportunities for speedups.

SkBlurDrawLooper.h 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.
