// from plugin registers some data from plugin address space in Qt metatype system, which is not being updated
// when plugin is unloaded and loaded again. Any subsequent calls to QVariant or other template classes/methods
// which use metainformation will result in a crash. It is likely (but not verified) that qRegisterMetaType leads
// to the same issue. Since we can not guarantee that plugin does not use Q_DECLARE_METATYPE or qRegisterMetaType
// we shall not unload plugin at all, to be safe rather than sorry.
//
// But it seems also that metainformation gets deleted BEFORE plugins are unloaded on application exit, so we can
// not call any metainformation-using code in destructors that get called on unloading. Since Qt classes themselves
// are using such calls (QGraphicsViewScene, for example), random crashes on exit may be a symptom of this problem.
//
// EditorManager is an exception, because it really needs to unload editor plugins, to be able to load new versions
// compiled by metaeditor. Editor plugins are generated, so we can guarantee to some extent that there will be no
// metatype registrations.
//
// See:
// http://stackoverflow.com/questions/19234703/using-q-declare-metatype-with-a-dll-that-may-be-loaded-multiple-times
