pgraph: Fix "Unknown render mode 5" errors

Browse Source 
This happened when a M_dual transparent object is given the
M_filled_wireframe render attrib. M_dual would copy the transparent
parts of the object to the transparent back-to-front bin, before
the M_filled_wireframe handler could deal with the M_filled_wireframe
flag.

The solution is just to switch the order - let M_filled_wireframe be
dealt with before the transparency code gets a chance to make a copy.
