The reason I didn't move osd_level to mpctx already is that the GUI code
references it. I think fixing such issues in the GUI would not be a good
use of time (unless someone turns up to do a big rewrite of the GUI code
- which doesn't seem to be happening - it'll probably have to be dropped
at some point in favor of external frontends). On the other hand it
wasn't worth it to let the GUI break over a minor improvement like this
alone so I've left it for later.

Maybe you misunderstood what I meant. I didn't mean justifying that
specific line. Rather I meant that because the patch has such changes
which make the code more complex and tricky (a negative thing) the
usefulness of the functionality added by the patch needs to be
justified. What kind of use cases do you have in mind for the patch?
