* Draws the outline of a 2D inclinded elliptical arc starting at "angle" and extending to angle +
* sweep, centered on the specified point, and contained in the XY plane (z=0). Note that "angle"
* is defined differently than it is for gluPartialDisk()! Uses an efficient parametric algorithm
* to avoid expensive calls to triginometric functions. Verticies are evenly spaced in parameter
* space. If "a" and "b" are equal, a circular arc will be rendered.
