[cairo] Drawing points?

Is there a recommended way of drawing points with Cairo?
I'm interfacing with traditional pen/pixmap drawing techniques, and
am trying to find an optimal match to how some toolkits expect to
be able to draw points. Specifically:
- The cap style controls whether the point is a dot or square.
- The lineweight controls the radius/size of the point.
- The resulting box/circle is centred over the given point.
I can probably kludge something together with combinations of
cairo_arc()/cairo_rectangle()/etc, but I'm not sure if that'd be
optimal - Both in terms of performance, and for what the various
backends could support natively for drawing points.
Many thanks for any suggestions/info!
