<p>This extension defines two port types: morph:MorphPort, which has a
host-configurable type, and morph:AutoMorphPort, which may automatically change
type when a MorphPort 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>
