Seeking in rawvideo in ffplay messes up vertical alignment

[Tjoppen]

If you play rawvideo in ffplay and click around the image will move vertically. Tested in current master (b70251c).

How to reproduce:

$ ffmpeg -i http://samples.mplayerhq.hu/DV-raw/voxnews.dv -t 1 -pix_fmt rgb24 -f rawvideo -y out.rgb24

Then run ffplay and click around:

Not a regression, horizontal shifts are also possible;-)

Not reproducible with time-seeking, but seeking with the mouse also breaks later time-seeking.
