Bug description:
  mir_demo_server(_minimal) version 0.13 and later: Window
  movement/resizing stops responding when the cursor leaves the surface.

  If you move or resize a surface with Alt+(button1/button3) then it's
  very easy to get the shell into a state where the window stops
  responding to movement/resizing and even becomes unrecoverable (window
  1px wide).

  Essentially the problem is the shell is only looking at the current
  cursor position and doesn't do anything if it's outside of the
  surface. This is frustrating as waiving the mouse around a bit it's
  very easy to reach this situation.

  It should be looking at the gesture as a whole and only doing position
  checking at the start of the move/resize gesture (ie. mouse button
  down). Thereafter the gesture should be continuous until the button is
  released, regardless of whether the cursor is still inside the
  surface/titlebar. You will find this is how all real desktops work,
  and mir_proving_server tries to too. Surfaces should always "own"
  input regardless of cursor position, just so long as the gesture
  (mouse down) began on that surface.

  The "unrecoverable" bit: This happens if you resize a surface too
  small/thin and it becomes impossible to resize it bigger again.
