  38 ; On entry:     R0 == pointer to a string
  39 ;
  40 ; On exit:      R0 == width of the string in OS units
  41 ;
  42 ; Use:          Returns the width of a string, as it would be displayed in
  43 ;               an icon (i.e. taking into account things like the current
  44 ;               desktop font etc.)  The width is exact, so if you want to
  45 ;               e.g. draw a box round it, you'll have to add on a little
  46 ;               clearance at each end.  8 OS units seems to be a good size
  47 ;               for the clearance (so the total width you'd use is given by
  48 ;               utils_strWidth(string)+16, because it has two ends).
