/**

 * Implements a tab to modify attributes to fill the padding of a polygon

 * such offset and separation (between pictures or markers).<p>

 * <p>

 * This tab is used several times in different places in our applicattion becuase the

 * behaviour is the same if the user is filling the padding of a polygon using pictures

 * or makers .For this reason, in order to avoid the repetition of code, this class has been

 * created (instead of treat it like a simple tab). With this solution, the user

 * only has to refer it to use it (and do not need to create a tab and fill it again

 * and so on).
