/**
 * Esta clase dibuja varios de los iconos que se usan a lo largo de todo el LookAndFeel.
 * Esta es la clase que hace el trabajo duro de pintar checkboxes, radios, sliders... Consta de 
 * varias inner clases privadas y de funciones que las dan acceso. Las inner clases mas o menos
 * son todas iguales: pintan un icono base leido de un archivo PNG, segun cual sea el estado del
 * objeto (seleccionado, inactivo...) le dan una capa de color y si es necesario vuelven a pintar 
 * otro icono.
 * Podria hacerse mas sencillo pintando un unico icono segun el estado del componente, teniendo
 * un PNG por cada estado, pero entonces no se podria usar colores en ellos porque si cambiara el
 * color de seleccion o foco, por ejemplo a verde, todos los objetos de la aplicacion se pintarian
 * seleccionados en verde menos los iconos, que se pintarian con el color con que hubieramos pintado
 * el PNG, dando un aspecto inconsistente. Por eso se pinta un icono trasparente y una capa de color
 * cuando hace falta, para decidir en tiempo real cual es el color apropiado.
