  46 ;               snippets of information, like the task handle we've been
  47 ;               given.  It also registers an exit handler so that the Wimp
  48 ;               gets closed down.

  80 ;               an icon (i.e. taking into account things like the current
  81 ;               desktop font etc.)  The width is exact, so if you want to
  82 ;               e.g. draw a box round it, you'll have to add on a little
  83 ;               clearance at each end.  8 OS units seems to be a good size
  84 ;               for the clearance (so the total width you'd use is given by
  85 ;               wimp_strWidth(string)+16, because it has two ends).
