I'd like to modify application code.

The sample code to be changed is here.
https://gerrit.automotivelinux.org/gerrit/#/c/16839/

The reasons why I'd like to change are

• WM changes the role by the following commit. We would like to change app code to align in GG.

https://gerrit.automotivelinux.org/gerrit/gitweb?p=apps/agl-service-windowmanager-2017.git;a=commit;h=cf05c2b5c92b9a79635aa2277a9d55449e14fab6

Graphics role is used for policy management in car use case, for example, which WM changes to navigation when car runs.  And the role and policy which windowmanager handles are desirable to be changeable by policy management designer. (*1)

But if we change the role to other one ( just small case in this case), it will not match to the argument of the event from homescreen. So I'd like to separate homescreen.

• Localize the homescreen problem

In my understanding, currently, homescreen is under re-considering design.

Current implementation of app uses the role to distinguish whether the event from homescreen is delivered for me or not.

If homescreen and windowmanager shares the role, homescreen's fix may causes some problems to window manager. So I'd like to separate homescreen.

(*1.) In my opinion, it is good to define pre-reserved role in AGL.
