involute or cycloid option

[Neon22]

What's involved in adding an option to draw cycloids instead of involutes. I know cycloids are not as good for high speed gears as they slide.
But for pin gears they work well, especially for gears with a very small number of teeth (where involutes do not work as well).
I'm inspired by Mattias's video for his excellent program:

Sprocket gears appear to be cycloid profiles.
That might mean we could indicate an involute, cycloid, pin, or sprocket gear as a type to initially choose from. Then a spur or ring gear.
I'm assuming a sprocket is some kind of special case of a cycloid.

I'll put this to the back of the queue. As long as we still have issues with involute gears, I'll focus on these.
