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.
The rendered picture should match the reference image, except as noted in the Test Description. In particular, the 'textLength' constraint must be satisfied precisely, and the basic rules associated with the "spacing" and "spacingAndGlyphs" values of 'lengthAdjust' must be met, but the precise algorithm for meeting all of the required contraints is otherwise unspecified.
