File src/gpu/SkGpuDevice.cpp (right):

https://codereview.chromium.org/616923004/diff/1/src/gpu/SkGpuDevice.cpp#newc...
src/gpu/SkGpuDevice.cpp:651: // try multisampled target if possible
Why don't we just pass the sample count of the SkGpuDevice's GrRenderTarget here
and use it?

That's what we do for saveLayer (the GrRT created for the layer copies the
sample count of the base SkGpuDevice's GrRT).
