Prevent calling GL functions with an invalid surface Bug: 18518580 When destroying CanvasContext, the surface can be invalid state. So the surface should be updated to null prior to destroying GL resources to ensure that GL functions are not called with an invalid surface. Some GL implementation makes an error if GL functions are called with an invalid surface.
