Add a pointer to wlsc_surface for shell-private data. This is a temporary solution. Add struct shell_surface, where you can add any shell-private data members related to a wlsc_surface. The getter function takes care of creating the private data if it does not exist yet. Not used anywhere yet. Signed-off-by: Pekka Paalanen <ppaalanen@gmail.com>
