MORX-17: Rearrangement with DontAdvance at End of Text

The font for this test case has an AAT Extended Glyph Metamorphosis Table with a single Rearrangement Subtable. Its finite-state machine contains a single state with the following transitions:

For glyph A, the transition carries the MarkFirst flag. No rearrangement action is performed.
For glyph B, the transition carries the MarkLast flag. No rearrangement action is performed.
For End of text, the transition carries the DontAdvance flag and performs a rearrangement action of type 1 (Ax ⇒ xA).
For any other glyphs, the machine performs no action.

The input string for this test case is AB. If your rendering system correctly implements Apple Advanced Typography, the A glyph should be rearranged to the end of the rendered string when your implementation executes the rearrangement for the End-of-text transition. Despite the presence of the DontAdvance flag, the result should be BA. See also fontkit bug 147.
