+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, 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.
