arcs take many parameters starting from the last point given by the previous segment and ending at a target xy
allow editing in three ways:
1: via bulge (point that the arc crosses through while adjusting endpoint thetas and radius)
2: via endpoint thetas (adjusting radius and bulge)
3: via radius (adjusting ...?)
