This is a tricky function that really needs a test around it. Also it has several assumptions and traps: - It will not work if the zones have multiple polygons in the poly sets - It will not work if any polygon has line chains in a different order - It is quadratic in number of zones and the compare itself is superlinear (Simplify is called, evilly in a const function, which is quadratic) and in a cyclic comparison, sort, which is presumably nlog-n ish. However, at least for the quadratic nature, profiling shows this to be absolutely insignificant even for the VCU118 board.
