| 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. |
