/**

 * PictureMarker allows the user to store and modify the properties that define a

 * <b>picture marker symbol</b>.<p>

 * <p>

 * This functionality is carried out thanks to a tab (simple marker)which is

 * included in the panel to edit the properities of a symbol (SymbolEditor)how is

 * explained in AbstractTypeSymbolEditor.

 * <p>

 * First of all, in the above mentioned tab the user will have options to change

 * the files from where the pictures for the symbol are taken (one for the symbol

 * when it is not selected in the map and the other when it is done).<p>

 * <p>

 * Secondly, the user will have options to modify the pictures which had been

 * selected before  (width and offset) .
