  <!-- We assume there is a gap of more than 1px between dashes. Hence
       putting two dashed lines with only one pixel of difference in their
       vertical coordinates should not render the same as one dashed line
       alone. The opposite is true for continuous line.
       The red squares allow to ignore the difference at the bounds -->
