public class SWTGraphics2D

extends java.awt.Graphics2D

An extension to Graphics2D to support an SWT Piccolo Canvas with little modification to the current Piccolo architecture There is an outstanding SWT bug request #33319 for more efficient polyline/polygon rendering methods. It also appears that most of the code below could be made obselete by bug fix #6490 A lot of this may also be duplicated in GEF - the eclipse Graphical Editor Framework
