Generates two arcs, intermediate point is evaluated at a point where the slopes are equal. (I believe this is logically coherent.)
Use case: drawing a four-leaf clover (e.g. one leaf is zero/up/right/zero)
This doesn't add much complexity to the state machine, but it does make validity and user experience far more difficult (on top of implementation being hard-ish).
