Since GLX and EGL are abstracted by Cogl the two backends are both implementing everything using the Cogl API and they are almost identical. This updates the egl backend to support everything that the glx backend supports. Now that EGL and GLX are abstracted by Cogl, the plan is that we will squash the clutter-egl/glx backends into one. Since the EGL backend in clutter can conditionally not depend on X11 we will use the EGL backend as the starting point of our common backend. https://bugzilla.gnome.org/show_bug.cgi?id=649826
