popup_dialog - do_dialog() used for popup dialogs. Allegro game programming library.

       Like do_dialog(), but it stores the data on the screen before drawing the dialog and restores it when the
       dialog  is  closed. The screen area to be stored is calculated from the dimensions of the first object in
       the dialog, so all the other objects should lie within this one.
