Maybe this should just be a static helper in SkGpuDevice.cpp since no other
subclass is using it (and it's only used in a couple targeted draw calls).

I'm using this in SkBitmapDevice as well - happy to refactor though if you have
something in mind.

Gotcha.. didn't catch that. Need it be a class member or can it be static?

made it static, good point.

     friend class SkCanvas;
