gui_mouse_x, gui_mouse_y, gui_mouse_z, gui_mouse_b - Hook functions used by the GUI routines to access

       Hook functions, used by the GUI routines whenever they need to access the mouse state. By  default  these
       just  return  copies  of  the mouse_x, mouse_y, mouse_z, and mouse_b variables, but they could be used to
       offset or scale the mouse position, or read input from a different source entirely.
