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.
