+ if 'qual' is 'first', then the match succeeds only if the first value matches.
+ if 'qual' is 'not_first', then the match succeeds only if any value other than
+ the first matches.
+ For match elements with target=font, if test 'target' is 'pattern',
+ then the test is applied to the pattern used in matching rather than
+ to the resulting font.
+
+ Match elements with target=scan are applied as fonts are scanned.
+ They edit the pattern generated from the scanned font and affect
+ what the fontconfig database contains.
