I've been involved in this discussion on IRC as well, so I just wanted
to say that from a high level I concur with what Henrik wrote above.

Beyond what Henrik wrote, I think there are ways to optimize the
architecture if a gesture is recognized as application specific.
However, the method I came up with was convoluted and tricky, so I think
we should continue with the architecture as it is and see if the extra
WM wakeups really are an issue. If they are we can take another look at
the convoluted tricky architecture (or just speed up wayland development :).
