bug:20063841 Restores old SkShader matrix behavior from before the Glop refactor. Many drawing operations draw without sending the canvas transform to the GL shader. In such cases, we need to adapt the matrix sent to the SkShader logic to invert the canvas transform that's built into the mesh. Change-Id: I42b6f59df36ce46436322b95bf9ad2140795ee58
