  WIP: high DPI scaling support in kwin.
  
  Surface events are all normalised by surface_scale
  Output is normalised to output_scale
  
  From a kwin POV this means:
  
  - we need to not assume texture size == client size. It will be off by a factor of surface scale.
  - we need to render at output_scale times the size of the output, to go from output normal to hardware
  
  This branch adds support for qpainter in x11windowed. It will be expanded over time.
  
  DO NOT MERGE AS-IS.
  
  - Set m_client size in surface normal co-ordinates
  - Scale QPainter x11 windowed backend
  - Scale input on windowed backend so input co-ordinate system matches host
  - Add warning about scene_openGL . Delete me in future squash
