In case we have a straight line, we place pylon only every two tiles, so there are certain tiles which we ignore.
A straight line is found if we have exactly two PPPs.

Which of the PPPs are inside the tile.
For the two PPPs on the tile border the following system is used: if you rotate the PCP so that it is in the north, the eastern PPP belongs to the tile.

Preferred points of each trackbit.
Those are the ones perpendicular to the track, plus the point in extension of the track (to mark end-of-track). PCPs which are not on either end of the track are fully preferred.
