+/** <p>This interface provides the means to transform between internal
+    coordinates in 100th of mm and screen coordinates without giving direct
+    access to the underlying view.  Each view forwarder represents a
+    specific real or virtual window.  A call to
+    <method>GetVisibleArea</method> returns the visible rectangle that
+    corresponds to this window.</p>
+
+    <p>This interface is similar to the SvxViewForwarder but
+    differs in two important points: Firstly the <member>GetVisArea</member>
+    method returns a rectangle in internal coordinates and secondly the
+    transformation methods do not require explicit mapmodes.  These have to
+    be provided implicitly by the classes that implement this
+    interface.  A third, less important, difference are the additional
+    transformation methods for sizes.  The reasons for their existence are
+    convenience and improved performance.</p>
+
+    @attention
+        Note, that modifications of the underlying view that lead to
+        different transformations between internal and screen coordinates or
+        change the validity of the forwarder have to be signaled separately.
