This is based on revision 360 of lp:qtubuntu.

Main features/bugs fixed:
- fix QQuickWidget-based app rendering
- wire up Qt window types to Mir to enable desktop-based applications
  to function with a window manager
- use QEGLPlatformContext and QEGLPBuffer instead of custom code
- correctly populate and update list of QScreens
- support for switching keyboard layouts
- improve window resizing to fix visual glitching
