OK, so basically for each mouse event generated by the server, it would also
generate a new 'relative mouse event'. This sounds fine to me too (after we
just need to decide if we duplicate the standard motion event content in
this new event - which would enable exactly what I propose at the price of
using more network bandwith when both are active at the same time - or if
this new event would contain only the new reportings).

BTW, is 'XExtMouseSelectInput' an existing X extension (I did not find
anything about it in my man pages on my (pretty old) X install or on Google)
or part of the new proposed extension ?

Anyway, when I find time (I will try to start next week), I will try to code
a 'proof of concept' patch that will (uncondionally) generate this new
relative mouse movement event on each mouse move. If this works, it will be
time enough to decide how to put this in the X server 'cleanly' (i.e.
creation of the extension, changing all the extension registering stuff,
extension activation / de-activation, ...).

Well, let's forget about this extension for now (I already have enough on my
plate with the mouse one which is more important). It may well be that after
I integrate the relative mouse movement handling in Wine, it will prove
unnecessary.

Anyway, thanks for your feedback.
