Draws a connected group of quadrilaterals. One quadrilateral is defined for each pair of vertices presented after the first pair. Vertices 2*n*-1, 2*n*, 2*n*+2, and 2*n*+1 define quadrilateral *n*. *N*/2-1 quadrilaterals are drawn. Note that the order in which vertices are used to construct a quadrilateral from strip data is different from that used with independent data.
