Define a width x height rectangle. The upper-left corner is at [x, y]. If either width or height is 0, the rectangle is not rendered. Use the RVG::ShapeConstructors#rect method to create Rect objects in a container.

Specify optional rounded corners for a rectangle. The arguments are the x- and y-axis radii. If y is omitted it defaults to x.
