Some updates to CameraController, Transformable
as well as FPSController
Cutaway is a Draggable, closable, bordered version of the CameraView.
CloseCutawayEvent is a custom event that can decouple the act of closing an arbitrary Cutaway from the 3D scene itself.
Eliminated unnecessary camera transforms.
