-    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
