We haven't tested all the TMD primatives, so it does look like 3D lines
is another one thats not supported. As for drawing 3D lines, you could
try a polygon with points the same (not at all ideal), or you could
perform your own transformation and then draw to the screen (still not
ideal, GsLINE is the structure, GsSortLine to add to ordering table).
I'll look into both methods, even though I'm not convinced about this
wireframe stuff (controvertial).
