I made a few perhaps controversial changes:
Also introduced two classes, PressableContainer and PressableSprite, to handle click targetting. I made a few assumptions in the implementation, the most important being that the Container object exists in some capacity as a 2d camera object for the scene. The other being that no one will be doing any viewport shenanigans. I haven't fully tested all viewport configurations. The implementation will be mostly performant unless the sprite tree is very deep (n>50).
