<h3 id="MORX-11">MORX–11: “End of Text” Rearrangement with MarkLast Flag</h3>

<div class="desc">
  The <a href="../fonts/TestMORXEleven.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 one single state with the following transitions:
</div>

<ul class="desc">
  <li>For glyph <em>A</em>, the machine sets both <em>start</em>
  and <em>end</em> of the <em>marked glyph sequence</em> to the current
  glyph position.</li>

  <li>For “end of text”, the machine changes the <em>end</em> of the
  <em>marked glyph sequence</em> to the current position and
  executes a rearrangement action of type 2, which moves the
  last marked glyph to the front of the marked sequence.</li>

  <li>For any other glyphs, the machine performs no action.</li>
</ul>

<div class="desc">
  The input string for this test case is <em>BABBAABX</em>.  If your
  rendering system correctly implements <em>Apple Advanced
  Typography,</em> the finite-state machine should have marked the
  last <em>A</em> (the third-last glyph in the input string) before
  taking the final end-of-text transition. When processing
  end-of-text, your implementation should first extend the <em>marked
  glyph sequence</em> to the trailing <em>ABX</em>, and then perform a
  rearrangement for moving <em>X</em> to the front of the marked
  sequence. See also <a href="https://github.com/devongovett/fontkit/issues/145">fontkit bug 145</a>.
