        * clutter/glx/clutter-backend-glx.c:
        * clutter/glx/clutter-backend-glx.h:
        * clutter/x11/clutter-x11-texture-pixmap.c:
        * clutter/x11/clutter-x11-texture-pixmap.h:
        General cleanup of texture pixmap code, adding;
          - Pixmap dimentions and depth now auto probed, read only props.
          - More X safety traps
          - Add support for optionally tracking damage and automatically
            updating texture.

        * clutter/glx/clutter-glx-texture-pixmap.c:
        * clutter/glx/clutter-glx-texture-pixmap.h:
        General cleanup and some safety additions. Needs more work so
        'proper' subclass - dependent on new COGL.

        * clutter/x11/clutter-backend-x11.c: (clutter_x11_remove_filter):
        Invert g_return_if check.

        * configure.ac:
        Pull in XComposite and XDamage (at least for now)

        * tests/Makefile.am:
        * tests/test-pixmap.c:
        Add a modified test from Johan for above.
