<h3 id="MORX-16">MORX-16: Rearrangement with DontAdvance and MarkFirst</h3>

<div class="desc">
  The <a href="../fonts/TestMORXSixteen.ttf">font</a> for this test case has
  an <a href="https://developer.apple.com/fonts/TrueType-Reference-Manual/RM06/Chap6morx.html"
  >AAT Extended Glyph Metamorphosis Table</a>
  with a single <em>Rearrangement Subtable</em>. Its finite-state machine
  contains two states (0 and 1) with the following transitions:
</div>

<ul class="desc">
  <li>For glyph <em>A:</em></li>
  <ul class="desc">
    <li>in state 0, the machine moves to state 1.
    This transition carries both the <em>DontAdvance</em> and
    <em>MarkFirst</em> flags. No rearrangement action is performed.</li>

    <li>in state 1, the machine moves to state 0.
    This transition carries no flags.
    No rearrangement action is performed.</li>
  </ul>

  <li>For glyphs <em>B, C,</em> and <em>D,</em> the machine stays
  in its current state. As a side effect, it sets the <em>end</em>
  of the <em>marked glyph sequence</em> to the current glyph position.</li>

  <li>For glyph <em>E,</em> the machine stays in its current state.
  As a side effect, it sets the <em>end</em>
  of the <em>marked glyph sequence</em> to the current glyph position,
  and executes a rearrangement action of type 1 <em>(Ax ⇒ xA).</em></li>

  <li>For any other glyphs and “end of text”, the machine performs
  no action.</li>
</ul>

<div class="desc">
  The input string for this test case is <em>ABCDE</em>.
  If your rendering system correctly implements <em>Apple Advanced
  Typography,</em> the <em>A</em> glyph should be rearranged to the
  end of the rendered string, resulting in <em>BCDEA</em>.
</div>
