Lathe, mesh, and plane objects now preview
using specific wireframing methods. I believe
I've also patched all primitives now, so
there shouldn't be any more crashing/freezing.

Non-linear spline lathe objects wireframe crudely;
instead of tesselating the spline between segment points,
I just connect the points directly.

Plane objects draw using a light gray color
to avoid competing with other objects.
