If the display has been setup up, we should destroy the underlying objects that the winsys has created. This can be done by calling the winsys->destroy_display() function in _free. Then, in that function, and for the NULL and GDL EGL platform we can destroy the surface we have created in the setup_display() function (through create_context()). This allows to have clutter create a "dummy" display in cogl_renderer_check_onscreen_template(), then free it, then recreate the context and the surface that will be the final ones. https://bugzilla.gnome.org/show_bug.cgi?id=655355
