equals
Rounded identity over the vertex cycle: equal when the vertex lists match pairwise at the SCALE quantum.
Starting vertex and traversal direction both count — the same loop entered at a different vertex, or traversed in reverse, compares unequal. Identity is exact-class: a subclass instance and a plain Polygon never compare equal.
Return
true iff other shares this object's exact class and its vertices all match after rounding.
Parameters
other
The object to compare against.
