Don't need Aspect, just adjusts for visible height angle.
Text centering failed for different FontSize - fixed.
Screen size same for a camang change. Now its done?
There's always something more?

well there are now much smaller remaining constants, 20 and 1.05.

Here's what you can do with it; IF you can rotate around an axis. I don't know
how in POV. vrotate() is not rotation(r,axis,pnt). If you cant, you need
triangulation.inc ... added centering option, and y adjust.
CamAng change, scale stays ...
