/** A helper interface for element presets.
 * This interface offers methods to query and manipulate parameter preset sets.
 * A preset is a bunch of property settings, together with meta data and a
 * name. The name of a preset serves as key for subsequent method calls to
 * manipulate single presets. All instances of one type will share the list of
 * presets. The list is created on demand, if presets are not used, the list is
 * not created.
 *
 * The interface comes with a default implementation that serves most plugins.
 * Wrapper plugins will override most methods to implement support for the
 * native preset format of those wrapped plugins. One method that is useful to
 * be overridden is property_names_vfunc(). With that, one can control which
 * properties are saved and in which order.
