[MPlayer-dev-eng] vf stereo3d comments

[compn]

saw this on irc, no time to investigate:

[14:43] <kriskropd> I think I found an error in the documentation 'abl
or above_below_right_first' under stereo3d - it should be s/abl/abr/
[14:43] <kriskropd> also, found a bug wit 'ab2l or
above_below_half_height_left_first' - instead of cutting the video
height in half, it cuts by width [14:43] <kriskropd> MPlayer SVN-r37379
