Subject: New concept of dynamically placing surfaces in static defined layout
 areas.

This is useful if an application wants to render more than one surface.
By default, one surface is placed in one layout render area. With the new homescreen.xml
introspection, apps can place their surfaces as they wish (limited to the boundries
of the assigned layou render area!).

The functionality is not fully implemented, but the shared lib already provides the interface.

+
+    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.

+  <!--
+    renderSurfaceToArea:
+    @surfaceId: The surface that is requested.
+    @renderArea: The render area inside the current layout area.
+
+    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
