the arguments, using the receiver's foreground color. The left and
right edges of the rectangle are at <code>x</code> and <code>x + width</code>.
The top and bottom edges are at <code>y</code> and <code>y + height</code>.
The <em>roundness</em> of the corners is specified by the
<code>arcWidth</code> and <code>arcHeight</code> arguments, which
are respectively the width and height of the ellipse used to draw
the corners.
