gluNextContour
Before the first contour is described, gluNextContour can be called to define the type of
the first contour. If gluNextContour is not called before the first contour, then the first
contour is marked GLU_EXTERIOR.
This command is obsolete and is provided for backward compatibility only. Calls to
gluNextContour are mapped to gluTessEndContour followed by gluTessBeginContour.
