+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.
