        * clutter/x11/clutter-x11.h:
        Create a new X11 backend class of which EGL and GLX 'real' backends
        then subclass. Effectively shares all X11 code between both backends
        avoids code duplication and brings many missing features to EGL X
        backend. Requires some cleanup and testing. (#518)

        * clutter/cogl/gles/cogl.c: (cogl_color):
        Add define to use color4ub only if configure finds it.
        If not fall back to old code.

        * configure.ac:
        Drop support for vincent checks.
        Drop sdles backend.
        Specifically check for color4ub call.
