REVISION SUMMARY
  While developing support for sub-surfaces it became obvious that there
  is a need for visualizing the tree of sub-surfaces.
  
  The surface-tree is a new mode added in the debug console. There are now
  two buttons to switch between the default window tree and the surface
  tree.
  
  The surface tree is a little bit more basic than the windows tree. The
  type of window (whether x11, wayland or internal) is ignored. All windows
  build up the top level with the sub surfaces as children.
  
  Each surface is represented by some basic information about it:
  
  - Client (binary path and pid)
  - internal surface id
  
  If the surface has a shared memory buffer mapped a scaled down version
  is used as the window decoration role.
  
  The model gets reset whenever the tree changes in some way as it's
  rather complex to track correctly and well, it's just a debug console.
  
  Currently the tree is not really functional yet as KWin doesn't announce
  support for sub-compositor protocol, which is also the reason for lack of
  autotests for the model. Will be added once sub-compositor works
  properly.
