+Performance optimizations for Internet Explorer
+
+by Thomas Frank and John Holdsworth.
+
+fillPolygon method implemented by Matthieu Haller.
+
+
+
+High Performance JavaScript Graphics Library.
+
+Provides methods
+
+- to draw lines, rectangles, ellipses, polygons
+
+	with specifiable line thickness,
+
+- to fill rectangles and ellipses
+
+- to draw text.
+
+NOTE: Operations, functions and branching have rather been optimized
+
+to efficiency and speed than to shortness of source code.
