Well we don't do that when snapping to guides and the grid either, and
as said before, it's a totally non-standard way of dealing with
snapping. The mouse pointer should always be driven by the user, not
by the application, and until recently, gtk didn't even have an API
to wrap the mouse, for just that reason.
We won't add that to GIMP.
