Difference
<text id="revision"> legend every test carries: it renders in a fallback font this
library cannot match, so it is excluded from the comparison entirely rather than failing every test.
In each test, the test string is in blue and the reference image is in black. The rendered picture should approximately match the reference image, however there is some question in the reference image concerning the exact amount of space in the long-space areas. The third test uses the nbsp unicode character to force the reference white spaces display, which provides an accurate match if the font in use has the same metrics for that character and the default white space. Also, variations are possible in the text fonts and layout (per CSS2 rules). The test also uses the 'rect' element, as well as basic fill (solid primary colors), stroke (black 1-pixel lines), font-family (Arial) and font-size properties.
