CenterStage Object Class:  OffsetCurve
Subclass of: CurveFromCurve

curve a certain distance long its normal direction.

The OffsetCurve class supports all the directives of the
CurveFromCurve class (other than the Function directive), plus the
following:

    Offset d

	This specifies the distance to offset the new curve from the
	original curve.
