0b7ba8e573 Do GeoM projection on CPU (#477) 
Handling GeoM projection on CPU may seem like a weird choice, given
how fast GPU is, but it pays off:

* You only have to do a very small subset of the actual matrix
  multiply.
* You don't have to construct a matrix in the vertex shader.
* Six fewer float32 values per vertex.
* You do still have to do the matrix computation for each vertex,
  though.
