commit 053bd5bf2425aed44e1c2bb981d98ee5171211a0
Author: Chris Wilson <chris at chris-wilson.co.uk>

    sna: Use the correct storage for box_from_seg
    
    Fixes regression from 3aa98289e3a2 with clipped segments. As we clipped
    the empty box rather than the segment, we never drew any outlines.
