MeshBuilder::with_prim_type does nothing

No matter what is passed to with_prim_type, the primitive type is always Triangles.

I'm not that familiar with the code base, but I poked around and from what I can see the primitive type isn't attached to anything. It's assigned in the mesh but never really used.

Yeah. That's because pipeline dictates primitive type. Mesh can't do anything more than checking that pipeline was built with correct primitive type.

I'm coming to see that. This is a bug in amethyst_renderer, not rendy specifically. It pushes everything through the same pipeline.
