  59  *   glass_windPointer *w == the window data from which the icon is from
  60  *   int i == the icon to update (-1 for the title)
  61  *   BOOL updateSize == whether to update the window's size variable

  63  *     string given what's in the data word.  Pass 0 if its actually a
  64  *     valid pointer
  65  *   void *handle == pointer to pass to 'proc'
