Geometry component doesn't work for single-size shapes

[morphogencc]

Teapot and Icosohedron don't work, but Sphere, Capsule, Cube work fine. I imagine this has something to do with Teapot and Icosahedron being created an unit scale, while the other shapes have functions to set their size in-line (e.g. .radius() or .size()).

I think the solution is to handle the scaling separately either as a ci::geom modifier (like ci::geom::Scale()) or as a part of the Transform component.
