TILEMAP_TRANSPARENT_COLOR: This works just like before and
even has the same type name. Create a tilemap of type
TILEMAP_TYPE_COLORTABLE and call
tilemap_set_transparent_pen() to specify which remapped pen
is transparent.
TILEMAP_BITMASK: This type is no longer special; with the new
code, any tile_get_info callback can specify a bitmask which
will be processed after rendering to make some pixels
