* clutter/clutter-main.c:
        * clutter/clutter-private.h:
        * clutter/clutter-stage.c:
        Rework and fix offscreen rendering, also rejig GLX
        context handling, moving mostly into stage.
        Require at least OpenGL 1.2 ( CLAMP_TO_EDGE )

        * clutter/clutter-texture.c:
        Explicity set props on _init() as to avoid nasty can_create
        bug failing miserably in certain situations.
        Switch to CLAMP_TO_EDGE for textures to avoid tile seams.
        Add some more GL error checks.

        * clutter/clutter-label.c:
        Extra debug info

        * configure.ac:
        Require gdk-pixbuf-xlib-2.0
