We lose. Mesa is not going to gain support for interclient fencing anytime
soon.

    sna/dri3: Mesa relies upon implicit fences for X/Compositor synchronisation

    The decision has been made that DRI3/intel shall continue with DRI2-style
    implicit fencing for synchronisation between X and clients using pixmaps
    as texture sources. (The other way around uses explicit fencing!)
