-Subject: [PATCH 2/3] ivi-id-agent: added ivi-id-agent
-
-This is a reference implementation of an ivi-id-agent plugin. It
-creates surface-ids for desktop-surfaces depending on the configuration
-provided in "weston.ini". For more please refer to the reference
-implementation in this commit.
-
-The only public interface available is the "id_agent_module_init"
-function. It is responsible for initialization of structs and reading
-the configuration.
-
-In the reference "weston.ini" two types of configurations can be found:
-
-[desktop-app] is used to configure a particular application. Therefore
-the desired surface-id must be provided. Moreover "app-title" is the
-title that is provided by the desktop application (xdg-protocol).
-"app-id" behaves accordingly. Although both parameters can be set, it
-is not mandatory. Finally at least one has to be set.
-
-[desktop-app-default] enables the id-agent to generate generic
-surface-ids for unconfigured applications, e.g. for development. This
-tag is optional. To generate the id an interval starting from
-"default-surface-id" to "default-surface-id-max" is used. The id is
-incremented until the interval is exceeded.
-
-In the function "get_id" a surface-id is assigned by means of the
-configuration. It can be adjusted, if another behavior is desired.
-In this plugin the parameters, that are described above, are evaluated.
-
-To use these patches please also apply the dedicated patches for
-weston: https://github.com/mtey/weston/tree/xdg_support_ivi_id_agent
-Since libweston-desktop is used to introduce desktop-surface support,
-xdg-protocol is supported.
