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.
