Detailed Description

OSG Implementation of DtWindowEllipseInstance.

Uses vrvGraphics to implement a 2D ellipse. Creates either a DtFilledPolygon or a vector of DtSegmentedLines. The vector of lines is so that the outlined ellipse can be clipped. A filled Ellipse using a DtFilledPolygon can be drawn using a start and end angle in rads, inner and outer dimensions. An outlined ellipse can be drawn with a start and end angle in rads, and a line width.
