[PATCH weston-ivi-shell 02/15] ivi application protocol:

[Nobuhiko Tanibata]

Add interface ivi_application, which creates ivi_surface objects tied
to a given wl_surface with a given id. The given id can be used in a
shell to identify which application is assigned to a wl_surface and
layout the surface wherever the shell wants. ivi_surface objects can
be used to receive status of wl_surface in the scenegraph of the
compositor.
