Two dynamic PhysicsBody2D nodes (one with a CircleShape2D collider, one with a
RectangleShape2D collider) fall under gravity and come to rest on a STATIC
PhysicsBody2D floor. The Physics2DWorld resolves the contacts automatically, so
each body settles exactly on top of the floor.


## What it demonstrates
- PhysicsBody2D(DYNAMIC) with two collider kinds: CircleShape2D and RectangleShape2D.
- PhysicsBody2D(STATIC) as an immovable floor the dynamic bodies rest against.
- Automatic gravity + impulse-based contact response from the Physics2DWorld.
- Different shapes settling at the correct height (floor top minus their extent).

Controls:
  R   - Reset the bodies back to their drop positions
  ESC - Quit
