[PATCH weston-ivi-shell v2 02/15] ivi application protocol:

Fri Mar 7 05:56:02 PST 2014


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.

Changes for v2:
   - Rename "error" to "warning" because meaning of "error" in wayland is fatal.
