That would be a way... concecutive rotate/translate and exotics (like shear
and perspecive distortions, which POV doesn't have primitives for) can be
collapsed into one "matrix".  However, a "matrix" with 16 parameters might
take more file space than a small number of rotate and translate commands.
So there is a break-even point.

And that might be a partial answer to my original question:  there is no
primitive to rotate the way I want, but I could use a POV matrix.
