[PATCH weston-ivi-shell v4 5/9] A reference implementation how to use weston-layout library.

Sun Mar 16 23:28:22 PDT 2014
The library is used to manage layout of surfaces/layers. Layout change is
triggered by ivi-hmi-controller protocol, ivi-hmi-controller.xml. A reference
how to use the protocol, see hmi-controller-homescreen.
In-Vehicle Infotainment system usually manage properties of surfaces/layers
by only a central component which decide where surfaces/layers shall be. This
reference show examples to implement the central component as a module of
weston.
Default Scene graph of UI is defined in hmi_controller_create. It consists of
- In the bottom, a base layer to group surfaces of background, panel,
and buttons
- Next, a application layer to show application surfaces.
- Workspace background layer to show a surface of background image.
- Workspace layer to show launcher to launch application with icons. Paths to
binary and icon are defined in weston.ini. The width of this layer is longer
than the size of screen because a workspace has several pages and is
controlled by motion of input.
