/**

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

 * polygon with a padding and an outline<p>

 * <p>

 * This functionality is carried out thanks to two tabs (picture 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 (picture fill)permits the user to select the picture for the padding and

 * differentes options to modify it such as the angle(<b>incrAngle</b>) and the scale

 * (<b>incrScaleX,incrScaleY</b>). Also, there is an option to select a color for the

 * fill (<b>jccFillColor</b>).

 * <p>

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

 * to change the separtion and the offset.
