It is a solution of the problem, but not so nice.
Combined mode (solid and wire) is used very often. The better way is to 
render poly as solid (usually, making gl list), then, call the list twice:
for solid face and wireframe.
Also, it solves the problem of outlined figures.
For now, we have duplicated (TWO) sets of points, polys etc. Insted of 
ONE, rendered twice (that is 10-200 times faster, I think, that separate 
drawing).
I do not know why not to make these feature available...
