SetHUDLayer

This method displays a complete Head Up Display in a graphic form. It accepts a serialized meta DC that is saved into a stream, and draws it on top of the 3D Window.

Note:    To constantly update the HUD, call this method on each OnDrawHUD event. If the HUD layer is permanent, call this method once. TerraExplorer maintains the HUD layer until another call to the method is performed.
