This attribute is mandatory and has to be specified whenever you create a Hollywood object. You cannot create an empty Hollywood object without an attached display.
By default, the widget won't be resizable. You can change this
by setting the Area.FixWidth and Area.FixHeight
False. In that case, your Hollywood widget will become
resizable and whenever the user resizes the window, your Hollywood
display will get a "SizeWindow" event which you can listen to using
InstallEventHandler() function. You can then react on
this event accordingly and redraw your display, etc.
