// whole ensamble becomes a single wire. Then you
// relabel it as a notgate again. The two wires
// which *were* distinct are still part of the same
// wire mesh.
// Problem solution:
// Here, when you apply a label to a group of
// substrokes, we will "explode" all the wire shapes
// that were changed (break them into single-substroke
// shapes). We expect that they will be reconnected
// later.
