Element: graphic_window.lug_display
Element: graphic_window.lug_displaynumeric
Whether or not entity lugs are to be displayed graphic_window is painted. A value of 1 indicates that they are, but only for entities with non-zero entity.lugs attributes. A value of 0 will suppress lug display. For new graphic windows its value is 1.
Although display of lugs can be suppressed in a window by use of this attribute, the function luglock which snaps to an entity lug will be executed the same way irrespective of whether a window's lug_display is on or off.
