  26 /*  FUNCTION
  27     Changes several attributes of an object at the same time. How the
  28     object interprets the new attributes depends on the class.
  29
  30     INPUTS
  31     object - Change the attributes of this object
  32     tagList - This is a list of attribute/value-pairs
  33
  34     RESULT
  35     Depends in the class. For gadgets, this value is non-zero if
  36     they need redrawing after the values have changed. Other classes
  37     will define other return values.
  38
  39     NOTES
  40     This function sends OM_SET to the object.
