/// This method allows for a tiled texture to be drawn in an auto-tiling mode.
/// This allows, for example, a grass patch on a tilemap to have nice looking edges that transfer over into a path without any hard edges between tiles.

///
/// This method is a more complex version of <see cref="DrawAutoTile"/> that overlays separate border textures on a base texture, which also allows for non-rectangular texture areas to be used easily.
/// For auto-tiling in this way to work, the tiles have to be laid out as follows: 17 tiles aligned horizontally within the texture file, with the following information:
