/*
Window restore session uses GetWorkspaceID()/MoveToWorkspace() differently
on Wayland.
MoveToWorkspace() is normally called when a window is visible/rendered and
widget code moves the window to a particular workspace. That approach doesn't
work on Wayland where an application can't position itself.
On Wayland we need to place the window before it's shown, so we use this
path instead:
1) In ConfigureToplevelWindowNative() we register an "xdg-toplevel-realized"
GTK signal handler to get notified when the xdg_toplevel window is created.
2) Block NativeShow() while mWaitingToSessionRestore is set. We can't show
the toplevel window until we have a window restore ID provided by a
MoveToWorkspace() call.
3) In MoveToWorkspace(), save the session ID and show the window. That fires
the "xdg-toplevel-realized" signal which gives us the xdg_toplevel and we
restore window state according to the session ID.
Likewise we use GetWorkspaceID() to create/save the xdg_toplevel session
for later restore.
