- Red circle is painted first onto a clean canvas - it is the 'destination'.
- Blue brick is then painted on the canvas. Its .globalCompositeOperation attribute is changed for each test. It is the 'source'.
- Different browsers render some of the tests in different ways (especially the CSS/SVG blending modes - from 'normal' to 'luminosity').
Known browser issues: ???
