reimar b0a88d1362 vf_stereo3d: Add support for converting to interleaved 3D 
Patch by Steaphan Greene [sgreene cs.binghamton.edu]

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@33648 b3059339-0415-0410-9bf9-f77b7e298cf2

Improve stereo3d interleaved man page description.

Patch by Steaphan Greene [sgreene cs.binghamton.edu]

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@33689 b3059339-0415-0410-9bf9-f77b7e298cf2

Change memcpy_pic to force it to never write to image parts between
width and stride if creating a row-interleaved format, otherwise
the second memcpy_pic might overwrite what the first wrote.
Changing the first should not be necessary but might result in
better performance.
