Subject: [PATCH] x11: With great power comes great responsibility, I guess.

The WL_SURFACE_ID messages force us to register SubstructureRedirectMask,
which means we have to participate in a bunch more stuff before windows
will resize and reconfigure properly. This fixes a bunch of problems with
real games.
