Entities can now specify per-tile sprite indices via the sprite_grid
property. When set, each tile in a multi-tile entity renders its own
sprite from the texture atlas instead of the single entity sprite.
API:
entity.tile_size = (3, 2)
entity.sprite_grid = [[10, 11, 12], [20, 21, 22]]
entity.sprite_grid = None # revert to single sprite
Accepts nested lists, flat lists, or tuples. Use -1 for empty tiles.
Dimensions must match tile_width x tile_height.
