The edge whose end the blend leaves from, along its tangent there.
The edge whose start the blend arrives at, along its tangent there.
OptionalmatchFalse matches the tangents at both ends with a cubic curve; true also matches the curvature there, with a quintic curve.
OptionalbulgeHow far the blend holds each tangent before it turns; larger values swing wider.
Two edges and the kind of join for
shapes.edge.blendBetweenEdges, which bridges the gap from the end of one to the start of the other with a smooth curve.
