    dri2: Invalidate DRI2Buffers upon SetWindowPixmap updates
    
    When transitioning to a redirected or unredirected Window, the Composite
    layer modifies the Window's Pixmap. However, the DRI2Buffer for the
    Drawable is still pointing to the backing bo of the old Pixmap with the
    result that rendering goes astray.
    
    This now also effects DRI2 Drawables that are touched by PresentPixmap.
