/**
 * This is the parent interface of all Symbolizers.
 * 
 * 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.
 * 
 * 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.
 * 
 * The details of this object are taken from the 
 * OGC Styled-Layer Descriptor Report (OGC 01-077) version 0.7.2.
 * 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.
 *
 * The graphical parameters and their values are derived from SVG/CSS2 
 * standards with names and semantics which are as close as possible.<p>
