next things i’d like it to do:
- a “smoothing” paramater to make the joins c2 or c3 continuous (for squircles or motion paths that don’t want sudden changes of speed)
- a parameter to alter the tangent of the join point (sometimes referred to as ptt in the literature for some reason that is over my head). and bonus points for controlling that angle with the length of the end controls to approximate how a bezier works
