* Move plugin/transform to plain transform.  This way transform can depend on
  model and GUI classes, but plugin doesn't have to.

+ * Metadata associated with a transform.
+ *
+ * The transform ID is the same as that used in the Transform class.
+ * It is intended to be computer-referenceable and unique within the
+ * application.
+ * 
+ * The name is intended to be human readable.  In principle it doesn't
+ * have to be unique, but the factory that creates these objects
+ * should add suffixes to ensure that it is, all the same (just to
+ * avoid user confusion).
+ *
+ * The friendly name is a shorter version of the name.
+ *
+ * The type is also intended to be user-readable, for use in menus.
+ *
+ * To obtain these objects, use
+ * TransformFactory::getAllTransformDescriptions and
+ * TransformFactory::getTransformDescription.
