Enables certain nodes only when approximately visible.

The VisibilityEnabler2D will disable [RigidBody2D], [AnimationPlayer], and other nodes when they are not visible. It will only affect nodes with the same root node as the VisibilityEnabler2D, and the root node itself.
Note that VisibilityEnabler2D will not affect nodes added after scene initialization.
[b]Note:[/b] VisibilityEnabler2D uses an approximate heuristic for performance reasons. If you need exact visibility checking, use another method such as adding an [Area2D] node as a child of a [Camera2D] node.

The VisibilityNotifier2D detects when it is visible on the screen. It also notifies when its bounding rectangle enters or exits the screen or a viewport.
