I've worked on this a bit the last few days and finally merged into develop.
The caching logic is now in ZathuraRenderer and pages are notified via their
associated ZathuraRenderRequest if they are cached or got removed from the
cache. Pages will now release the surface themselves once they are not cached
and not visible.
There are still some workarounds that I'm not fully happy with and I'll probably
end up implementing some signals for the visibility stuff to make things easier.
Feedback is very welcome.
