The rectangle to add, specified in user space coordinates.
The horizontal size, in user space coordinates, for rounded corner sections.
The vertical size, in user space coordinates, for rounded corner sections.
An affine transform to apply to the rectangle before adding to the path. Defaults to the identity transform if not specified.
This convenience method is equivalent to a move operation to start the subpath followed by a series of arc and line operations that construct the rounded rectangle. Each corner of the rounded rectangle is one-quarter of an ellipse with axes equal to the
corner parameters. The rounded rectangle forms a closed subpath oriented in the clockwise direction.
