<strong><code>IMG_ARC_PIE</code></strong> and <strong><code>IMG_ARC_CHORD</code></strong> are
mutually exclusive; <strong><code>IMG_ARC_CHORD</code></strong> just
connects the starting and ending angles with a straight line, while
<strong><code>IMG_ARC_PIE</code></strong> produces a rounded edge.
<strong><code>IMG_ARC_NOFILL</code></strong> indicates that the arc
or chord should be outlined, not filled. <strong><code>IMG_ARC_EDGED</code></strong>,
used together with <strong><code>IMG_ARC_NOFILL</code></strong>, indicates that the
beginning and ending angles should be connected to the center - this is a
good way to outline (rather than fill) a 'pie slice'.
