/* Custom widgets: Loading custom widgets is a 2-step process: PluginManager

* Designer is not initialized yet.
* Later on, in ensureInitialized(), the plugin instances (including static ones)
* are iterated and the custom widget plugins are initialized and added to internal
* list of custom widgets and parsed data. Should there be a parse error or a language
* mismatch, it kicks out the respective custom widget. The m_initialized flag
* is used to indicate the state.
* Later, someone might call registerNewPlugins(), which agains clears the flag via
* registerPlugin() and triggers the process again.
* Also note that Jambi fakes a custom widget collection that changes its contents
* every time the project is switched. So, custom widget plugins can actually
* disappear, and the custom widget list must be cleared and refilled in
* ensureInitialized() after registerNewPlugins. */
