Show a Modal Window.
Similar to GUI.Window, however the window will always be on top of all other GUI, and while displayed, is guaranteed to be sole recipient of all GUI input and events. While a ModalWindow is being displayed, other controls will not be processing input. Note that only one ModalWindow can be displayed at a time.
