<para>
Draws a circle with its middle point at (<parameter>x</parameter>,
<parameter>y</parameter>). The circle starts and ends at position
(<parameter>x</parameter>+<parameter>radius</parameter>,
<parameter>y</parameter>). If this function is called outside a path it
will start a new path. If it is called within a path it will add the circle
as a subpath. If the last drawing operation does not end in point
(<parameter>x</parameter>+<parameter>radius</parameter>,
<parameter>y</parameter>) then there will be a gap in the path.
