From: Ning Tang <ning.t...@intel.com>
Since now toytoolkit and simple programs use shell_surface to show on
screen, we add it in tablet-shell to let them show.
But we only need serveral feature in tablet shell, the wl_shell is too
big and not suitable for tablet-shell.
And it is helpful to fill in the interface of wl_shell for now. Then we
could make toytoolkit, efl applications run against tablet-shell.
And this won't influence our work to differenciate tablet-shell to
dekstop-shell. Once wl_shell was modified in wayland protocol, we will
change this part too. We will add tablet_shell interface when it is necessary.
Now once a shell_surface is requested, it will be centered on screen and
have a black background surface.
We reserve the set_fullscreen method and all other implementation is
just return.
