This is only tangentially related:

Would something related to this be the preferred way to set up a scene so that
an object would occupy a specific position on the screen - back calculating to
determine where the camera should be?

So, let's say there are 2 views (I think that might be necessary to get Z), each
showing the same cube (and maybe a reference point like the origin) from a
different vantage point.
I'm presuming that a matrix would be the best way to reverse-project back to
where the camera should be?

It's just something that struck me with the functions, and matrices, and
user-define camera...
