+/** @file elrail.c
+ * This file deals with displaying wires and pylons for electric railway systems.
+<h2>Basics</h2>
+
+<h3>Tile Types</h3>
+
+We have two different types of tiles in the drawing code:
+Normal Railway Tiles (NRTs) which can have more than one track on it, and
+Special Railways tiles (SRTs) which have only one track (like crossings, depots
+stations, etc).
+
+<h3>Location Categories</h3>
+
+All tiles are categorized into three location groups (TLG):
+Group 0: Tiles with both an even X coordinate and an even Y coordinate
+Group 1: Tiles with an even X and an odd Y coordinate
+Group 2: Tiles with an odd X and an even Y coordinate
+Group 3: Tiles with both an odd X and Y coordnate.
+
+<h3>Pylon Points</h3>
+<h4>Control Points</h4>
+A Pylon Control Point (PCP) is a position where a wire (or rather two)
+is mounted onto a pylon.
+Each NRT does contain 4 PCPs which are mapped to a byte
+variable and are represented by the DiagDirection enum:
+
+A wire that ends on the PCP has a dark ending, otherwise the end is bright.<p>
+
+Now on each edge there are two PCPs: One from each adjacent tile. Both PCPs are merged
+using an OR matrix (i. e. if one tile needs a PCP at the postion in question, both
+tiles get it).
+
+<h4>Position Points</h4>
+A Pylon Position Point (PPP) is a position where a pylon is located on the ground.
+Each PCP owns 8 in (45 degree steps) PPPs that are located around it. PPPs are numbered
+0 to 7 with 0 starting north and numbering in clockwise direction. Each track bit has PPPs
+that are impossible (because the pylon would be situated on the track), preferred (because
+the pylon would be rectangular to the track). PPPs are represented by the Direction enum.
