Need to support pointer confinement in Mir and toolkits using Mir

[Brandon Schaefer]

We need to support pointer confinement set by the client. This way we can generate relative mouse events on a surface without the cursor being able to leave the edge of the window.

[Daniel van Vugt (vanvugt)]

I'm not sure we need to support displaying the cursor when it's confined.

It might be OK to just implement grabs, always hide the cursor then and leave it up to the client (which in the case of a VM might draw its own software cursor, like games do too).

The mir branch was the first step, not the 100% solution in mir.

xmir could probably reuse some of pointer confinement and warping support posted for xwayland this week
