Was there more of a performance gain when removing calls to Jo?

Jo Engine uses the SGL functions, so the speed gain would be marginal.
I never used Jo Engine sprite and math functions in this version of the engine.
The main gains I got are precision (all math functions with angles have 12 bits precision vs 8-9 bits for Jo Engine), better audio (sequence audio vs pcm streaming) and the biggest boost is RAM usage (huge gain).
But Jo Engine is a work in progress, I think once it has its own 3d functions it could be interesting to revisit.
