RE: [Geobject-core] ARS (or the lack thereof) and other things

Well, most of the time you know what you're working with in the case of
my example, so my code would work in those cases.  That was my
assumption.
=20
Actually, your example won't work because you've created a new
PlanarAngle (during the call to convert), and haven't set it on the Arc.

		 If you don't want to hold on to the angle separately,
just call:    ((PlanarAngle)arc.getOrientation()).setAngle(3.1415,
Angle.radians);

=09
	except this could lead to class cast exceptions, cos we're only
guaranteed=20
	an OrientationSource, not a PlanarAngle.  to oneline it, we'd
hafta call:=20

=09
((PlanarAngle)arc.getOrientation().getOrientation().convert(PlanarAngle.
class, null)).setAngle(3.1415, SI.RADIAN);=20

	...and it's debatable whether i even got that line right...=20

	and then, we'd have a new PlanarAngle (possibly, anyway), not
the arc's real OrientationSource,=20
	so there isn't a way to oneline it, i don't think.=20

	so if we want to make use of the OrientationSource's event
firing, we must hang onto=20
	the angle for the life of the arc?  eesh, ima gonna just make
new Orientations whenever i need 'em.=20
	there may be some cases where i can hang onto the original
Orientation i assign to the arc,=20
	but i don't anticipate very many.=20
