    Commit 4fc5dd00 ("compositor: add capability CAPTURE_YFLIP")
    introduced a capability flag which indicates whether y-flipping is
    necessary. As already indicated in that commit message, it seems
    that pixman flipps the y-axis only due to historic reasons.
    
    Drop y-flipping and use the WESTON_CAP_CAPTURE_YFLIP flag to
    indicate that y-flipping is not necessary. This simplifies code
    and improves screen share performance (on my test by about 3% down
    to 18% CPU load on the sharing instance of Weston).
