690c3cf981 graphics: Embed 'scale' part of the color matrix 
If the color matrix includes only 'scale' part, they are embedded
into vertices in order to reduce draw calls.

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.
