/**

 * FFrame used for embedding a View in the Layout. The View is not actually

 * inserted on the Layout, but it is used together with the MapContext in order

 * do draw an image which is then painted on the FFrame. Therefore, no

 * MapControl is used in current implementation, but a similar behavior is

 * simulated by the FFrameView. The original MapContext is cloned when assigned

 * to the FFrameView, which is then used for drawing.

 *

 * The FFrameView and the associated View can be synchronized, depending on the

 * values of {@link #getTypeScale()} and {@link #getLinked()}.

 *

 * The main synchronization logic is kept on two internal classes:

 * {@link OwnMapContextListener} and {@link ViewDocListener}. The first one

 * listens for events on the FFrameView and synchronizes the View accordingly.

 * The second one listens for events on the View and synchronizes the FFrameView

 * accordingly. There synchronization process is flagged using

 * {@link #b_updating} and {@link #b_updating}, in order to avoid incurring on

 * infinite synchronization loops.
