 /*! Retrieve the layout direction of the window titlebar: this includes the standard window buttons (close/minimize/maximize buttons) and the title for this window. In general, this will return "right to left" (RTL) if the primary system language is RTL. The layout direction may be RTL even in applications that do not have a RTL language localization. This value should be utilized if an application uses titlebarAppearsTransparent and places controls underneath the titlebar.
