On some platforms we can ask the GL context machinery to create a GLES context, instead of a GL one. In order to ask for a GLES context at GdkGLContext realization time, we use a bit field like we do for forward compatible, or debug contexts. The 'use-es' bit also changes the way we select a default version, because OpenGL and OpenGLES versions differ. https://bugzilla.gnome.org/show_bug.cgi?id=743746
