/**

 * <b>MarkerFill</b> allows the user to store and modify the properties that fills a

 * polygon with a padding made of markers and an outline<p>

 * <p>

 * This functionality is carried out thanks to two tabs (marker fill and MarkerFillProperties)

 * which are included in the panel to edit the properities of a symbol (SymbolEditor)

 * how is explained in AbstractTypeSymbolEditor.<p>

 * <p>

 * The first tab (marker fill)permits the user to select the marker for the padding and

 * other options such as the color for the fill (<b>btnChooseMarker</b>),to select the

 * ouline (<b>btnOutline</b>)and the distribution (grid or random) of the marker inside

 * the padding (<b>rdGrid,rdRandom</b>).

 * <p>

 * The second tab is implementes as a MarkerFillProperties class and offers the possibilities

 * to change the separtion and the offset.
