As Owen says, Proximity is primarily a tablet thing.
Many tablet technologies will tell you when the pen is near, but
not yet touching the screen; these events are for that purpose (in
the XInput extension).
This hasn't been very common, but may become much more common, as
Microsoft's tablet PC spec requires proximity, and if those become
common, we may start to have applications that care about proximity
notification.....
Note that many/most current touchscreens do *not* report proximity, only
actual contact, and it would not be appropriate for doing so....
For better or worse, you'll likely have to clean up the input
stream from the touchscreen, if it is reporting spurious events.
