If your list is of triangles, three vertices with the same coordinate
will give a degenerate  triangle -- one that is guaranteed not to
render.  Similarly, use four of the same vertices for a quad, etc.

It should be pretty easy to add support for zero-length vertex lists;
I'll look into it for pyglet 1.2.
