number y
- The position to draw the object (y-axis).
number r (0)
- Orientation (radians).
number sx (1)
- Scale factor (x-axis).
number sy (sx)
- Scale factor (y-axis).
number ox (0)
- Origin offset (x-axis).
number oy (0)

Notes
SpriteBatch does 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 OpenGL from processing the sprite when drawing the SpriteBatch.
