Draws a portion of a circle with at middle point at
(<parameter>x</parameter>, <parameter>y</parameter>). The arc starts at an
angle of <parameter>alpha</parameter> and ends at an angle of
<parameter>beta</parameter>. It is drawn counterclockwise (use
<function>ps_arcn</function> to draw clockwise). The subpath added
to the current path starts on the arc at angle <parameter>alpha</parameter>
and ends on the arc at angle <parameter>beta</parameter>.
