It essentially applies the image_map as an 'orthographic' projection onto scene
objects, devoid of perspective... which is quite different from a typical
map_type 0 projection.

Yes, I get that part.

So, as best I can tell, he's simply done the kind of thing that's done in the
"make this object/text always face the camera"... with the matrix.

but the image_map is converted to a function that incorporates x/z and y/z which
also corrects for the projection matrix so that everything lines up no matter
how near or far.

I just haven;t had the time to figure out how to start applying his include to a
scene, so that I can reverse-engineer it enough to provide a didactic diagram
and explanation.

So if you have working code....   ;)
