Probably can take GrDrawBatch here (and other Appends). Also should probably doc
that this must be a batch returned by the above Create.

I can't unfortunately because lastBatch on GrDrawTarget returns a GrBatch. 

+            GrColor color,
             const SkMatrix& viewMatrix,
             const SkRect& rect,
             SkScalar strokeWidth,
             bool snapToPixelCenters);
 
 };
