A notional camera in a scene defined by a point in space and the directional vectors describing its orientation. A viewport relates a camera to a render target, in this case a render UI widget. The viewport can be set to only cover some of the target's area, so multiple cameras can render into the widget in different places. By default cameras are instantiated as primary cameras and by default see all scene objects whose visibility settings haven't been changed. By setting a camera to be seconday it will by default see no scene objects except those Figure objects which explicitly makes themselves visible to that specific camera.

Get the projected ray from a point on the screen, (x,y) are real render target (widget) screen coordinates if `isAbsolute' is true, otherwise (x,y) are relative screen proportion values ranging over the unit square. In either case the top left corner of the camera's view area is (0,0), the bottom right is (w,h) for view area w-by-h pixels or (1,1) for relative coords.
Reimplemented in OgreCamera.
