/**

 * FMap's WMS Layer class.

 *

 * Las capas WMS son tileadas para descargarlas del servidor. Esto quiere decir que

 * est?n formadas por multiples ficheros raster. Por esto la fuente de datos raster (IRasterDatasource)

 * de la capa FLyrWMS es un objeto de tipo CompositeDataset. Este objeto est? compuesto por un array

 * bidimensional de MultiRasterDataset. Cada uno de los MultiRasterDataset corresponde con un tile

 * salvado en disco. Estos MultiRasterDataset se crean cada vez que se repinta ya que en WMS a cada

 * zoom varian los ficheros fuente. La secuencia de creaci?n de un CompositeDataset ser?a la siguiente:

 * <UL>

 * <LI>Se hace una petici?n de dibujado por parte del usuario llamando al m?todo draw de FLyrWMS</LI>

 * <LI>Se tilea la petici?n</LI>

 * <LI>Cada tile se dibuja abriendo una FLyerRaster para ese tile</LI>

 * <LI>Si es el primer dibujado se guarda una referencia en la capa WMS a las propiedades de renderizado, orden de bandas,

 * transparencia, filtros aplicados, ...</LI>

 * <LI>Si no es el primer dibujado se asignan las propiedades de renderizado cuya referencia se guarda en la capa WMS</LI>

 * <LI>Se guarda el MultiRasterDataset de cada tile</LI>

 * <LI>Al acabar todos los tiles creamos un CompositeDataset con los MultiRasterDataset de todos los tiles</LI>

 * <LI>Asignamos a la capa la referencia de las propiedades de renderizado que tenemos almacenadas. De esta forma si hay

 * alguna modificaci?n desde el cuadro de propiedades ser? efectiva sobre los tiles que se dibujan.</LI>
