d_menu_proc - Dialog procedure implementing a menu bar object. Allegro game programming library.

       This  object  is  a  menu  bar  which  will  drop  down  child  menus when it is clicked or if an alt+key
       corresponding to one of the shortcuts in the menu is pressed. It ignores a  lot  of  the  fields  in  the
       dialog  structure,  in  particular  the  color is taken from the gui_*_color variables, and the width and
       height are calculated automatically (the w and h fields from the DIALOG are only used as a minimum size.)
       The dp field points to an array of menu structures: see do_menu() for more  information.  The  top  level
       menu  will  be  displayed as a horizontal bar, but when child menus drop down from it they will be in the
       normal vertical format used by do_menu(). When a menu item is selected, the return value  from  the  menu
       callback  function is passed back to the dialog manager, so your callbacks should return D_O_K, D_REDRAW,
       or D_CLOSE.
