+/** GstPreset â 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.
