[fpc-pascal] GLM library alternative?

I see FPC has a matrix class but it doesn’t include all the helpers in GLM like rotation, transform, perspective transforms (https://open.gl/transformations). If I knew enough I think I could just build these myself but I’ll likely introduce a bunch of errors at first.

I use my own vector/matrix library VectorUtils3, which is written in 
plain C (thereby FPC friendly), and included in the common code of my 
OpenGL demo library:

Actually, there is also an FPC version of VectorUtils, FPC interfaces to 
most of my common code, and even a bunch of demos that I made FPC for. 
(Modern OpenGL, not old-style code, no immediate mode.) I never uploaded 
them anywhere, since there didn't seem to be much interest, but if 
someone wants them, no problem.
