  <P>
  The line dash pattern controls the pattern of dashes and gaps used to stroke paths.
  It is specified by an <I>array</I> and a <I>phase</I>. The array specifies the length
  of the alternating dashes and gaps. The phase specifies the distance into the dash
  pattern to start the dash.<BR>
  
  @param       phase       the value of the phase
  @param       unitsOn     the number of units that must be 'on' (equals the number of units that must be 'off').
