PathOfTravel.FindStartsOfLongestPathsFromRooms

Description:
For a floor plan view, calculates paths from points inside rooms to the closests of the destinations. Returns the start points of the longest path(s). If multiple paths have the same longest length, returns multiple start points.

Remarks:
The entire plan is divided in small tiles, and the distance to the closest destination point is calculated for each tile center point. Only tile center points that are located in rooms in the view are taken into account.
