-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.

+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, polygons, ellipses and arcs
+- to draw text.
+NOTE: Operations, functions and branching have rather been optimized
+to efficiency and speed than to shortness of source code.
