+ It can be invisible, then it is not shown on the screen. Or the state is unknown.

+ This function can be used to request, if it is allowed to render an application of a specific category
+ in a layout area. The idea is to decide from an application point of view to allocate recources or not.
+ Example: an application will decide to render video based on this call. This call will not change anything, it is only a request.

+
+ This is a special case. In the normal use case, one layout area is always filled completely
+ with the first surface, that the process creates (more precise: the surface with the lowest id).
+ By using this function, an app can request to position a different surface in the layout area.
