This patch allow going gst-inspect-1.0 on these elements removing ugly crash that was previously occurring. The method consist of making the widget creation as lazy as possible. This way we don't endup doing gtk_init() before the application. We also ref_sink() the widget, so we don't crash if the parent widget is discarded, and cleanly error out with GL if the widget has no parent window, because calling gtk_widget_realized() can only be done if the widget has been parented to a window).
