Here is the caller graph for this function:

void set_graphics_state	(	boolean	show_graphics_val,
		int	gr_automode_val,
		enum e_route_type	route_type
	)

Sets the static show_graphics and gr_automode variables to the desired values. They control if graphics are enabled and, if so, how often the user is prompted for input.

Here is the caller graph for this function:

void update_screen	(	int	priority,
		char *	msg,

Updates the screen if the user has requested graphics. The priority value controls whether or not the Proceed button must be clicked to continue. Saves the pic_on_screen_val to allow pan and zoom redraws.
