 *  -----------------------------------------------------------------------------
 *  The scala2d package defines/redefines Java2D shapes (see java.awt and
 *  java.awt.geom).  The shapes are divided into five groups based on their
 *  dimensionality as well as their base type (class/trait):
 *  Basic:
 *      BasicStroke
 *      Dimension
 *      Shape
 *      Graphics
 *      Graphics2D
 *      RectangularShape
 *  0D:
 *      R2 redefines java.awt.geom.Point2D.Double
 *  1D:
 *      //CurvilinearShape is introduced and the following subtypes are defined
 *      Line    extends Line2D
 *      QCurve  extends QuadCurve
 *      Arrow   Line with an arrowhead
 *      QArrow  QuadCurve with an arrowhead
 *  1-2D:
 *      Path redefines java.awt.geom.Path2D.Double with subtypes
 *      Polygon
 *      Triangle
 *      Quad
 *      Pentagon
 *      Hexagon
 *      Octagon
 *  2D:
 *      RectangularShape redefines java.awt.geom.RectangularShape with subtypes
 *      Arc
 *      Ellipse
 *      Rectangle
 *      RoundRectangle
 *  Note:
 *      CubicCurve is currently not supported
