Support near & far clipping for the objects: Add a "Z" property to the camera (and a "frustum" size property, with an option to disable/enable near/far clipping) which will be compared against the object's Z property (or the rendering layer's Z property) and hide the object if it's not inside the viewing frustum (https://en.wikipedia.org/wiki/Viewing_frustum), i.e if the object is too close or too far from the camera.
