copy of the texels in VRAM rather than a readback and re-upload. This
gives a 3-10X speedup on recursive canvas-to-canvas draws.
N.B.: This introduces a new GM test, which will need new baselines.

Remove the imageblur test from gmslides.gypi for now, since SkPicture output
is incorrect. SkImageFilter is not flattenable, so the output is black.

SkBlurImageFilter, sets it on an SkPaint, passes that paint to saveLayer(),
draws the primitives which are to be blurred, then calls restore(), which
applies the blur. The blurs have separate sizes in the horizontal and vertical
direction. This feature is GPU-only for now.
NB: Due to the clipping change, there are slight pixel differences on the
blurs_gpu and shadows_gpu tests, so those will require rebaselining on all
platforms, as will some of the WebKit layout tests (TBD).
