 * A set of factory functions for drawing stroked rectangles either coverage-antialiased, or
 * non-antialiased. The non-antialiased ops can be used with MSAA. As with other GrDrawOp factories,
 * the GrPaint is only consumed by these methods if a valid op is returned. If null is returned then
 * the paint is unmodified and may still be used.
