+host-configurable type, and morph:AutoMorphPort, which may automatically change
+type when a MorphPort's type is changed.  These ports always have a default
+type and work normally work in hosts that are unaware of this extension.  Thus,
+this extension provides a backwards compatibility mechanism which allows
+plugins to use new port types but gracefully fall back to a default type in
+hosts that do not support them.</p>

+<p>This extension only defines port types and properties for describing morph
+ports.  The actual run-time switching is done via the opts:interface API.</p>
