There are times when we want to present to the user additional information that is overlaid on the current screen. This could take, for
example, the form of a window with a Yes or No question that the user needs to answer for the game. In this recipe, we will create a new
GuiWindowCtrl control that we will present to the user over the top of the current screen content, and have this window dismissed when the user clicks on a button.
For this recipe we will be working with the GUI Editor. We begin by starting up our game (such as the one built using the
Full template) and at the Main Menu section, pressing F10 to launch the GUI Editor.
