Bug#646075: gdm3's greeter can be moved into unusable locations

Package: gdm3
Version: 3.0.4-3
Severity: normal

It appears to be possible to move the gdm3 greeter into an unusable
position on the screen:

 * hold down alt, and right-click on the greeter.

 * choose "move" from the menu that pops up

 * move the greeter to the corner of the screen so nothing is visible
   by dragging the mouse.

Now, when someone tries to log into the machine, they won't be able to
find the place to enter a username or password.

This is particularly problematic for a lab setting, where one person
can (without authenticating themselves at all) leave the machine in an
on but unusable state.

I suspect that the greeter window should not be movable at all.
