Notes
SpriteBatches do not support removing individual sprites. One can do a pseudo removal (instead of clearing and re-adding everything) by:
SpriteBatch:set(id, 0, 0, 0, 0, 0)
This makes all the sprite's vertices equal (because the x and y scales are 0), which prevents the GPU from fully processing the sprite when drawing the SpriteBatch.
