Subject: sub: enable sub-pos with libass

The --sub-pos option and sub-pos property control the vertical position
of a subtitle.

Also change how sub-pos is handled in the old subtitle renderer (used
with -no-ass). The new behavior doesn't render subtitles out of the
screen if the subtitle is located near the top screen border and has
too many lines.
