Pointer motion while a button is held down does not change the focus, 
right? (ie same as mice).

So the only way this happens is if the client or server actively changes 
the focus or if the current focus is destroyed.

Any solution should be similar to any solution for keyboard keys and 
mouse buttons (even if it is just "these buttons are in class 1, these 
in class 2, these in class 3, etc...), so that it is possible to talk 
about all devices with buttons in the same documentation.
