Yes, I think in the long run we want raw input being passed to clients
and then to rely on the toolkits to do the right thing.
However I won't flick that switch until Qt's input resampling is usable
for us. That might be possible after we do frame notification, and have
more accurate and steady frame timing independent of nesting.

Clients can't get high resolution input in Unity8

Bug description:
Clients can't get high resolution input in Unity8.
Using native (non-nested) Mir servers, clients can get the full speed
input stream if they so choose (MIR_CLIENT_INPUT_RATE=0). And it's
planned that this will become a formal API feature: bug 1439590
However in Unity8, because it is a nested server, the client no longer
has the option of getting this high resolution input.
Examples of clients that utilize high resolution input for improved visual
quality:
mir_demo_client_fingerpaint -w--desktop_file_hint=unity8
mir_demo_client_target -n--desktop_file_hint=unity8
You may also want to experiment with those using ultra-high resolution input
by adding a kernel parameter: usbhid.mousepoll=1
This is a tricky problem because for touch at least we do want the
input stream to be throttled to the display rate from the top level
down. Perhaps the answer is to enhance Unity8 to be a full-speed (non-
resampled) client and then the clients of Unity8 can then still have a
choice of whether they get resampling or not.
