/**

 * <p>

 * SmartTextSymbolLabelClass.java<br>

 * </p>

 *

 * <p>

 *

 *   This is a <b>wrapper</b> to be able to use a SmartTextSymbol as a

 * LabelClass. A SmartTextSymbol uses a line instead of a point.

 * Being in fact a Line and not a Marker, it does not make any sense

 * to have label styles since the label styles are well-defined rectangle

 * areas where texts are placed in fields backgrounded by an image. In this

 * contexts, the area is defined dinamically for each line, and there is no

 * sense to have texts fields. They will be rendered as a single string

 * along a line.<br>

 * </p>

 * <p> The label itself is the SmartTextSymbol,

 * the geometry (the line), the label expression,

 * and the text applied to the symbol.<br>

 * </p>

 * <p>

 *   Most of the operations performed by this LabelClass are in fact

 * delegated to the symbol.<br>

 * </p>
