Adi's changes broke layer resizing before they are attached to the layer hierarchy.

Also fixed a drop into the debugger when starting Tracker: fRootLayer is now NULL
in the constructor of WinBorder - which is not fatal, as we only wanted to get
the screen size (which was formerly managed by RootLayer).
