DRAW RANGE ELEMENTS CONFORMANCE
Jon Leech, SGI (ljp@engr.sgi.com)

Coverage:
	Create a CallDrawRangeElements() like CallDrawElements().

Conformance:
	To be defined.

	There *are* no conformance tests for DrawElements(), which makes
	it hard to extend to DrawRangeElements() (which is essentially
	untestable in any fashion different than DrawElements() in any
	case, since behavior on invalid indices is undefined).
