What is orth_scale and orth_shift? #29

Hi, Thanks for open-sourcing the project.

I am studying how to rasterize the FLAME mesh onto a tri-plane. In the code here, the vertices of the FLAME mesh is shifted and scaled by the pre-defined orth_shift and orth_scale. Could you please tell me what the purpose of this shifting and scaling operation? Is it used to align the FLAME mesh with the camera pose?
