{@link java.awt.Shape} implementations used for the
rendering of geographic features. Some classes in this package are just
ordinary Java2D
shapes (for example {@link org.geotools.renderer.geom.Arrow2D}, which can
be used for rendering wind fields). Some other are more elaborated: they
extend {@link org.geotools.renderer.geom.Geometry}, which has support for
setting the
{@linkplain org.geotools.renderer.geom.Geometry#setCoordinateSystem coordinate system},
{@linkplain org.geotools.renderer.geom.Geometry#setRenderingResolution rendering resolution},
etc. Those classes are not designed for spatial analysis or topology: they are
not a replacement for JTS,
neither an implementation of ISO-19107. They are rather wrapper around arbitrary source
of (x,y) coordinates to be rendered.
