Follow-up Comment #20, bug #58956 (project octave):

You are probably right.
It very much looks like we need something similar to that change. And if we
should find a better solution, we can still change what we have so far.
So I cleaned up the patch and pushed it here:

You are understanding the applied transformations better than I do. So please
tell me if this doesn't make any sense:
Would it be possible to use a different coordinate system for the final
rendering? E.g. one that has its origin in the center of the scene that is
rendered and the camera position (possibly far out) on the negative z-axis?
That might relax issues with large single precision floating point numbers
(whose neighbors are "sparse").
