  31 /*  FUNCTION
  32         Change the attribute of the given gadget according to the
  33         attributes chosen in the tag list. If an attribute is not
  34         provided in the tag list, its value remains unchanged.
  35
  36     INPUTS
  37         gad -     Gadget, for which the specified attributes should be set for.
  38                   May be be NULL. If so this functions does nothing.
  39         win -     Window, in which the gadget is.
  40         req -     Not used. Specify NULL for now.
  41         tagList - List of attributes to set.
