/** FormEditorW is a singleton that stores the Designer CoreInterface and
* performs centralized operations. The instance() method will return an
* instance. However, it must be manually deleted when unloading the
* plugin. Since fully initializing Designer at startup is expensive, the
* class has an internal partial initialisation stage "RegisterPlugins"
* which is there to register the Creator plugin objects
* that must be present at startup (settings pages, actions).
* The plugin uses this stage at first by calling ensureInitStage().
* Requesting an editor via instance() will fully initialize the class.
* This is based on the assumption that the Designer settings work with
* no plugins loaded.
*
* The form editor shows a read-only XML editor in edit mode and Qt Designer
* in Design mode. */
