Adds magnifier functionality to gnome-shell.

Browse Source 
Adds the ability to create one or more zoom regions that show magnified or
enhanced views of the desktop.  The magnifier provides options for:
* magnification factor,
* four mouse tracking modes common to screen magnifiers,
* positioning the magnified view in one of four screen location, or full screen,
* crosshairs to accentuate the position of the mouse,
* user preferences persistence via GConf (schemas in
  .../data/gnome-shell.schemas).
* a DBus API to allow other processes to drive the magnifier as a service.
