Detailed Description

KisRootSurfaceInfoProxy is a special proxy object for the surface color management information of the widget.

When created, the proxy does the following:

1) Finds the top-level widget that watched belongs to. (is watched changed its parent in the meantime, e.g. during construction, then the proxy will handle that as well)

2) Finds the QWindow that this toplevel widget is painted on (if platform window is not created yet, subscribes to QPlatformSurfaceEvent to attach when platform window is finally created)

3) Finds KisSRGBSurfaceColorSpaceManager object attached to this window. This object is usually attached with an event filter in KisApplication to all windows not having a special property (if the manager is not yet attached, tracks its addition by filtering QChildEvent)

4) Finally, connects to the manager and forwards its sigDisplayConfigChanged() to local sigRootSurfaceProfileChanged()
