Fill()

bool ZONE_FILLER::Fill	(	const std::vector< ZONE * > &	aZones,
		bool	aCheck = false,
		wxWindow *	aParent = nullptr )

Fills the given list of zones.

NB: Invalidates connectivity - it is up to the caller to obtain a lock on the connectivity data before calling Fill to prevent access to stale data by other coroutines (for example, ratsnest redraw). This will generally be required if a UI-based progress reporter has been installed.

Caller is also responsible for re-building connectivity afterwards.
