gnome-mag is a magnification API used by gnopernicus. The last only add
logic to the magnifier be more suitable for the user.

I also thinked that this could be a true and the magnifier focus can be
going away if we implement these filters.

I think that implement it throw composite management is the easiest way,
because the idea in this case is present the screen like you want to the
user. If don't need the cool effects that can be achieved throw the use
of composite you could implement it only using Xlib calls, so you
application get's a lot of free throw differente environments, but I
think that you can get in troubles here, since I think that two
composite managers can't run together.
