This CL forces all GrSurface copies to go through a GrSurfaceContext (rather than GrContext). There is a bit of goofiness going on here until read/writePixels is also consolidated in GrSurfaceContext and a proxy-backed SkImage/SkSurface is added. This is a reland of https://skia-review.googlesource.com/c/5773/ (Add a deferred copy surface) Change-Id: Ib8fd96d0569274ef781366eb900ed8ee839ae9bd Reviewed-on: https://skia-review.googlesource.com/6109 Reviewed-by: Brian Salomon <bsalomon@google.com> Reviewed-by: Brian Osman <brianosman@google.com> Commit-Queue: Robert Phillips <robertphillips@google.com>
