I'll defer to Harry and Dan about if it *should* be done.  If it
*should* be done, I'll do it.

None of the HIDs has a problem with arcs that have arbitrary angles.
See http://www.delorie.com/pcb/pullit-sample.png

However, gerber is limited to drawing CIRCULAR arc segments, not
ELLIPTICAL arc segments.  To support non-circular arcs, we'd have to
draw them as a series of short line segments.
