+Performance optimizations for Internet Explorer\r

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