This smacks of the old X inability to make a decision and commit to a
direction. We can be very clear about this: Ubuntu won't support
multiple simultaneous competing gesture engines. We're already in
conversations with Qt et al to ensure they can work with utouch, and
we'll enhance the interface to allow apps to leyer their own
interpretation on the raw data. But there will be a single gesture
engine, and it will see the data before anything else does.
