Detailed Description

View - maintains a master camera view and a list of slave cameras that are relative to this master camera.

Note, if no slave cameras are attached to the view then the master camera does both the control and implementation of the rendering of the scene, but if slave cameras are present then the master controls the view onto the scene, while the slaves implement the rendering of the scene.
