 // TODO: Make two variations on this class: One for GrDrawState that only owns regular refs
 // and supports compatibility checks and changing local coords. The second is for GrOptDrawState,
 // is immutable, and only owns pending execution refs. This requries removing the common base
 // class from GrDrawState and GrOptDrawState called GrRODrawState and converting to GrOptDrawState
 // when draws are enqueued in the GrInOrderDrawBuffer.
