A rounded rectangle is a rectangle with rounded corners. The figure is defined by
the rectangle itself, along with the width and height of the ovals forming the
corners (called the diameters of curvature), as shown in Figure 13-5. The corner
width and corner height are limited to the width and height of the rectangle itself; if
they are larger, the rounded rectangle becomes an oval.
