Good, let me know if you find any cases that cause problems.

It's a good thing you guys chimed in on this bug, otherwise it
would have continued to have gone unnoticed by since I'm working
on other things presently.

Yeah, that's actually my code. I intend to support non-orthogonal
volume texturing, but there's an issue with convincing OpenGL to
shear the automatically generated texture coordinates that I have
to solve before it'll work correctly. The "VolumeSlice" textures
are done correctly however, as they are implemented differently.

Time. There never seems to be a lack of demand for new features.. :)
