Rootless X on Mir

Registered by kevin gunn

This blueprint contains work to implement and support a "rootless" X on top of mir in order to support legacy X apps in a Unity8/mir configuration

Whiteboard

Trusty is released, PLEASE SEE https://blueprints.launchpad.net/ubuntu/+spec/client-1410-mir-rootlessx

A bunch of these work items probably belong in a dependency blueprint - Mir On The Desktop

Note "Synaptics" is a brand. And most touchpads supported by the X "synaptics" driver are not made by Synaptics. So it's probably a good idea to name libsynaptics as libtouchsomethingelse, rather than prolong the confusion Xorg has created.

Note, work around SDL has identified another need that will be covered under the rework around the Mir input stack.
That is to include pointer warping and motion events.
related is https://bugs.launchpad.net/mir/+bug/1276322

SDL's input requirements will be satisfied with a Viewport flag on a MirSurface - triggering pointer confinement (when focused) and relative motion event delivery - and a WarpPointer API that takes the pointer to a specified point on an application's (focused) surface.

A later addition to the Viewport flag will be opt-in keyboard-bypasses-WM behaviour, so apps which require delivery of keys that are normally eaten by the Shell (eg: <alt>+<tab>, Windows key) can receive them.
