Native GTK apps in Mir

[Daniel van Vugt]

That's odd. GTK apps are running fine on my cleanly installed utopic 
laptop. It's just the desktop that's crashing. I could easily have 
broken that desktop, somehow. So assume it still works. Certainly it 
does work on a clean utopic laptop I've just tried.

Amending the instructions so they're more likely to work:

sudo -s
apt-get install mir-demos
mir_demo_server_shell --vt 1 &
env XDG_RUNTIME_DIR=/run/user/1000 \
     DISPLAY="" \
     MIR_SOCKET=/tmp/mir_socket \
     /usr/games/gnome-mahjongg
# Ctrl+Alt+F1

Incomplete features you are expected to encounter:
   * Menus
   * Dialogs
   * Non-arrow cursors
   * Mir touch event support not implemented - mouse only?
   * Random crashes/non-starting apps

But it's still nice to have something on screen. And to be able to run 
utopic's desktop apps unmodified inside Mir is quite nice.
