816fb314a4 graphics: Adjust texel positions for consitency
On second thought, given pixel coords represent a center of texels...

7c66d884d4 graphics: Adjusting position is no longer needed
Now pixel position is treated as left-upper in linear filter

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.
