TTFQuery has been updated to feel a tiny bit more modern.  It's still pretty old-school, but it now has some actual documentation, and should be more friendly for pip installation.

Found the bug that has been holding up my testing on PyOpenGL/OpenGLContext.  The shadow demos had been broken, which I considered a blocker.  Turns out not to have been related to the double->float conversion, instead, I left out the rotation axis normalization in the new transformation-matrix-calculation library. Duh!
