Highjacking the ChangeProperty and DeleteProperty vectors is a pretty fragile
and clumpsy way to receive window property updates. Consider eg. multiple
drivers and hotplugging: when they're unplugged in different order than they've
been plugged (and both drivers doing that hack), who knows what happens.
Instead use the hook infrastructure we already have since 1997: Xace.
Listening on property changes that way is pretty simple, doesn't suffer from
the mentioned problems and only takes 1/4 of the code.
