One side effect is that the SkShader's (or implicit shader's) fragment processor is responsible for the transition from an unpremul paint color to a premul color.

This makes the blurcircles bench go from ~33us to ~8us on Windows desktop.
It will require layout test suppressions

The existing mask effect code in Ganesh is subject to snapping issues (when the created mask is redrawn). This artifact can be seen by rendering the original geometry (w/o blurs) and comparing that result to a rendering of the unblurred masks. W/o this patch the results do not match up (they are arbitrarily shifted by a pixel).
This patch will require rebaselining and suppressions.
Chromium layout tests suppressions are here:

This is split off of https://codereview.chromium.org/1225923010/ (Start tightening correspondence betweeen GrDrawContext and GrRenderTarget). It:
fixes some style nits
replaces some passing of GrContext with GrTextureProvider & GrDrawContext
does a bit of the finer grained creation of GrDrawContexts

Adds a new FBO type kStencil_MSFBOType that is selected whenever
NV_framebuffer_mixed_samples extension is available. In this new
FBO type a non-msaa color buffer is created with a multisampled
stencil buffer attachment.
Replaces numSamples() with separate numColorSamples and numStencilSamples
methods in RenderTarget.
In mixed samples mode non-MSAA codepaths are used to draw simple shapes,
while NVPR-rendered paths and text are rendered with a multisampled
stencil.

This CL is ugly but it:
removes the stored SkGpuDevice back pointer from GrTextContext (at the cost of passing more parameters)
moves SkGpuDevice::internalDrawPath to GrDrawContext::drawPathFull
Unfortunately, the GrTextContext-derived classes still need the SkGpuDevice for filterTextFlags calls but I will try removing that in a separate CL.
