That looks like the bind operation to me. Why do you need a
new protocol?

So, you are OK with being asked *every time* if you accept that VLC
is trying to go fullscreen? I most definitely am not :D

This is why we wanted to let distro devs decide for their users what
the default policy should be. We then need to have a good UI for users
to realize that the application is running in fullscreen mode (following
what chrome and firefox are doing is likely a good idea).

However, Jasper has a point that we need to be sure that we can
override the policy in a consistent way across all backends. I have a
plan for this.
