Is it necessary to rebuild mplayer after updating libass?

[Sindhudweep Sarkar]

I noticed on the lucid-changes mailing list that libass was recently
updated. https://lists.ubuntu.com/archives/lucid-changes/2010-March/007954.html

At one point mplayer used libass for subtitle rendering. I have not
looked at mplayer or its packaging in quite some time, but I'm
guessing this is still true. Does the changed libass lib have the same
api or does mplayer use its own internal copy of libass?
