We have to use this function for wxWindowDC implementation and setting drag-and-drop icons, even though it is deprecated, as this API can't be implemented otherwise, so suppress the deprecation warnings about doing it. Also include the private GTK header in the Cairo wxGraphicsContext implementation just to avoid the deprecation warnings there too.
