* Columns are vertical sections of the viewport that are half a tile wide.
|

* The origin, i.e. column 0, is through the northern and southern most tile.
|

* This means that the column of e.g. Tile(0, 0) and Tile(100, 100) are in
|
||
* column number 0. The negative columns are towards the left of the screen,
|
||
* or towards the west, whereas the positive ones are towards respectively
|
||
* the right and east.
|
||
* With half a tile wide is meant that the next column of tiles directly west
|
||
* or east of the centre line are respectively column -1 and 1. Their tile
|
||
* centers are only half a tile from the center of their adjoining tile when
|
||
* looking only at the X-coordinate.
