Tested-by: Carlos Garnacho <carlosg at gnome.org> on all the remaining 3 patches.

Tried on mutter/gnome-shell master and touch on clients works nicely
(tested on xinput test-xi2 and gtk3 apps running with the X11
backend), so does pointer emulation (seen on xev, emacs,...). I've
only found issues when dragging client-side decorated windows (thus
gtk3 forced to run on x11) with touch, windows do wiggle when dragged.
Window dragging on touch triggers the same codepaths than dragging on
non-EWMH compliant WMs do (so based on raw XMoveWindow based on event
root coordinates).

I don't think this bug is intrinsically related to these patches
though, given gtk+ works fine on plain X11, it could also well lie in
mutter's configure request handling or Xwayland surface placement.
I'll investigate nonetheless, but IMO this is too weird and unlikely
to block these patches, which are already a vast improvement for these
devices.

Cheers,
  Carlos
