Query the current rendering viewport size.

Report an error.

Enables you to check whether there are any outstanding references on this object, other than the interface reference through which you are calling, and therefore whether this object will actually be deleted if you call its release method.

Sets the background colour, by colour name.

Sets the background colour.

Set control state for built in testbed controls, based on mouse movement.

Supply a target position that can be used to adjust camera target distance during camera control interactions, for more intuitive behaviour.
