Detailed Description

A Display with a Frame.

Camera derives multiply from Frame and Display. Its update() method calls both Frame::update() and Display::update(), marking the Frame as dirty and marking the Display for redrawing.

Camera computes its projection matrix after its compute tree has been called (see message::Compute_Receiver).

If two cameras are part of the same frame hierarchy, one call to the root frame's update() will suffice for redrawing both displays.
