- Feature: [pbs] Implement autoplacement of pbs blocks, when a block has an entry and an exit pbs signal, covert the entire block to pbs. Can be turned off in the patch settings. - Feature: [pbs] Allow showing of reserved status by making the tracks darker, when the pbs debug level is at least 1.

Five arrays are used to encode the information of the contents of each tile. These arrays are referred to as "<span style="font-weight: bold;">map_owner</span>", "<span style="font-weight: bold;">map2</span>", "<span style="font-weight: bold;">map3_lo|_hi</span>", "<span style="font-weight: bold;">map_type_and_height</span>" and "<span style="font-weight: bold;">map5</span>". The known encodings are listed in the table below. The most important value is the class of a tile, stored in the upper 4 bits of the type_and_height array. The lower 4 bits are used to encode the height and slope data. For a graphical represenation of the tile-layout have a look at <a href="landscape_grid.html">Landscape grid</a> page.

OTTD's class-specific periodic tile processing routine is called once every +256 ticks for each tile.
