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.
