  * GrRenderTarget represents a 2D buffer of pixels that can be rendered to.
  * A context's render target is set by setRenderTarget(). Render targets are
  * created by a createTexture with the kRenderTarget_SurfaceFlag flag.
  * Additionally, GrContext provides methods for creating GrRenderTargets
  * that wrap externally created render targets.
