-		@surfaceId: The surface that is requested.
-		@renderArea: The layout render area in which the given surface is located.

+		@layoutArea: The layout area where the application shall be rendered. Find the layoutArea ids in the layout definition!
+		@allowed: Returns true, if the application is allowed to be rendered in the area
 
-		Before an application uses renderSurfaceToArea to render a surface into an area inside a layout area,
-		this method should be used to get the dimension of the layout area, in which the surface
-		currently is positioned.
+		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 one surface. By using this function, an app can request to position a surface in the
-		layout area.
-		Example:
-		If the layout area is 500x500 pixel in size, the normal use case qould be, that a surface
-		is positioned at x=0, y=0 with a width and a size of 500. With this function, an application can position surfaces
-		free in this area.
-		E.g.: Position surface 101 at x=10, y=30, width=300, height=100 and 
-		surface 104 at x=100, y=130, width=30, height=10
+		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.
