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 02-070) version 1.0.0.
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.
