Tile Mapping Settings
This dialog is used to define the tile specification used by the tile
mapping functions (see menu Colors).

Width and Height define the dimension of a single tile
Number of Colors per Tile defines the colors that can be used at
maximum for a tile
Also you need to set up the maximum Number of Tile Palettes that
can be used
Ignore tile palette index 0 means that each tile may use the color
index 0 of any tile palette without producing an error when using the error
detection functions. This mode helps to create tiles that are using the index
0 as transparent. In this case the tile palette does not matter because every
tile palette's index 0 is seen as transparent.

functions for more information.
