Well, that is for gnome.  Users shouldn't be tied with gnome just to get
good zoom of gtk applications, and we want good zoom of other widget
libraries too, so we need a window magnification interface which is
independent from gnome.

But that means it'll only benefit the gnome shell, and not other
desktops.  Writing a *good* magnifier, which means not only just the
graphical effect, but also mouse tracking, focus tracking, smooth
transition, etc. is not something that we want to see having to be
implemented several times for several desktops, there are not enough
people who have the skills, context, and time to do that.
