// Purpose: A helper that measures the extents of the only non-NODRAW face of
//			its only solid sibling. Writes the extents as four vector keyvalues:
//
//				lowerleft
//				upperleft
//				lowerright
//				upperright
//			
//			ASSUMPTIONS:
//
//			1. Only one solid sibling.
//			2. That solid only has one face with a texture other than "toolsnodraw".
