	modeling tool.
	The camera is moving relative to the target with the mouse, by pressing either
	of the three buttons.
	In order to move the camera, set a new target for the camera. The distance defines
	the current orbit radius the camera moves on. Distance can be changed via the setter
	or by mouse events.
