    sna/dri2: SWAP_THROTTLE is also used for a delayed SWAP

    If there is already a pending operation on the drawable, the swap is
    queued. It is queued with SWAP_THROTTLE which classes with the
    vblank_mode=0 chaining, so the choice is to either review all other uses
    of SWAP_THROTTLE and duplicate the chain swap handling, or to choose when
    use to the alternate copy or back buffer. This patch opts for the
    latter.

    Fixes regression from
