It's redundant. The multipass clip loop is already done at a higher
level via the tnl run_render() function. As it was, primitives were
being rendered 2X times. Apps which did blending, like gloss, were
showing the problem.
It appears to me that the tdfx_render_vb_*() functions can only be
called via the tnl->Driver.RenderTabVerts pointer and that pointer
is only used inside the multipass loop in run_render(). If there's
another way for the tdfx_render_vb_*() functions to be called then
we've got a problem to fix.
