/**
 * This is the parent interface of all Symbolizers.
 *
 * <p>
 * A symbolizer describes how a feature should appear on a map. The symbolizer
 * describes not just the shape that should appear but also  such graphical
 * properties as color and opacity.
 * </p>
 *
 * <p>
 * A symbolizer is obtained by specifying one of a small number of  different
 * types of symbolizer and then supplying parameters to overide its default
 * behaviour.
 * </p>
 *
 * <p>
 * The details of this object are taken from the <a
 * href="https://portal.opengeospatial.org/files/?artifact_id=1188"> OGC
 * Styled-Layer Descriptor Report (OGC 02-070) version 1.0.0.</a>
 * </p>
 *
 * <p>
 * Renderers can use this information when displaying styled features,  though
 * it must be remembered that not all renderers will be able to fully
 * represent strokes as set out by this interface.  For example, opacity may
 * not be supported.
 * </p>
 *
 * <p>
 * The graphical parameters and their values are derived from SVG/CSS2
 * standards with names and semantics which are as close as possible.
 * </p>
