-/**
-   State Extension Data.
-
-   When the plugin's extension_data is called with argument LV2_STATE_URI,
-   the plugin MUST return an LV2_State structure, which remains valid for the
-   lifetime of the plugin.
-
-   The host can use the contained function pointers to save and restore the
-   state of a plugin instance at any time (provided the threading restrictions
-   for the given function are met).
-
-   The typical use case is to save the plugin's state when a project is saved,
-   and to restore the state when a project has been loaded. Other uses are
-   possible (e.g. cloning plugin instances or taking a snapshot of plugin
-   state).
-
-   Stored data is only guaranteed to be compatible between instances of plugins
-   with the same URI (i.e. if a change to a plugin would cause a fatal error
-   when restoring state saved by a previous version of that plugin, the plugin
-   URI MUST change just as it must when ports change incompatibly). Plugin
-   authors should consider this possibility, and always store sensible data
-   with meaningful types to avoid such compatibility issues in the future.
