[FFmpeg-cvslog] dsputil: use vertical component for drawing bottom edge.

[Ronald S. Bultje]

ffmpeg | branch: master | Ronald S. Bultje <rsbultje at gmail.com> | Wed Jan 25 17:17:52 2012 +0800| [c3af52fa8bbd6f1c5c0c70af89b02ff5b394f21d] | committer: Ronald S. Bultje

dsputil: use vertical component for drawing bottom edge.

Current code only writes 8 pixels of vertical edge for YUV422, which
causes MC artifacts when subsequent frames use data from that edge.
