Handle this render state similarly to D3DRS_ZFUNC, by mapping it in the
client DLLs.

As far as I can tell, save for the fact that it's only supposed to apply
to lines forming a convex outline, it's roughly equivalent to
D3DRS_ANTIALIASEDLINEENABLE. We definitely handled it the same way.

Curiously, even though we supported the render state, we didn't set the
corresponding capability bit. Do that now.
