I suspect that, while locked, we still don't actually want to expose
the various x and y properties for the mouse.  I agree with Vincent
that the *other* mouseevent properties are all useful, though, and
that the delta properties are really useful in non-mouselock
situations.

We should just zero all the position information.  Even if we can
switch all OSes to a delta mode, the position will be arbitrary and
meaningless.  This seems easier than making a new type of mouse event
that exposes all of normal mouse events except the position, and
ensuring that the two stay in sync when we add new info.
