-		this method should be used to get the dimension of the layout area, in which the surface

+		This function can be used to request, if it is allowed to render a surface in a layout area in preparation
+		of the real renderSurfaceToArea command. 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.
