The callback is passed:
- code (range 00-FF, contents of the first tilemap RAM byte)
- color (range 00-FF, contents of the first tilemap RAM byte). Note that bit 6
seems to be hardcoded as flip X.
The callback must put:
- in code the resulting tile number
- in color the resulting color index
- if necessary, put flags for the TileMap code in the tile_info
structure (e.g. TILE_FLIPX)
