Determines whether the PolygonCollider2D's shape is automatically updated based on a SpriteRenderer's tiling properties.
When this is true, the Collider's shape is generated from a SpriteRenderer, if one exists as a component of the parent GameObject. The shape generated is dependent on the SpriteRenderer.drawMode. Regeneration happens when the
autoTiling property is set to true, and subsequently every time a change is detected in the associated SpriteRenderer.
