complex divisibility check to let setters immediately know certain puzzle-parameter combinations are unsolvable. **2023-12-13** Fixed a regression in the knob interface noticed by @PinkHoodie - parameters can now be edited normally again **2023-12-16** Territories are now colorised and a recent regression found by @placeholder was fixed.
