This attempts to implement the gtkglsink element on Windows using WGL, as there were some more gotchas that are along the way, since we need to juggle with libepoxy along the way, meaning that we need a recent GTK+-3.24.x for this to work properly, i.e. the upcoming GTK+-3.24.43. Since we are essentially using an overlay compositor only during rendering, move its initialization and destruction into the gtk_gst_gl_widget_render() function, so that things are safer as we are doing things across threads between gstreamer (gst-gl) and GTK, as GL operations, as above, have more gotchas on Windows.
