        This tests setting and getting the <tt>currentScale</tt> attribute of
        the <b>SVGSVGElement</b> interface.
      </p>
      <p>
        There are three sub-tests, each represented by a rectangle (blue for
        pass, red for fail). The test has been passed if all three rectangles are blue, and
        the test slide is shown at 90% of its regular size (i.e., the
        range (0, 0) -&gt; (533.333, 400) user units is shown).
      </p>

      <p>
        The first sub-test checks that the initial value of
        <tt>currentScale</tt> is 1.  The second checks setting
        <tt>currentScale</tt> to a valid value (in this case, 0.9), and
        looks at the resulting screenCTM.  The third exercises retrieving
        the newly set value.
      </p>
