pango-font-description-better-match (desc old-match new-match)

desc -- a pango-font-description instance
old-match -- a pango-font-description instance, or nil
new-match -- a pango-font-description instance

True if new-match is a better match.

Determines if the style attributes of new-match are a closer match for desc than those of old-match are, or if old-match is nil, determines if new-match is a match at all. Approximate matching is done for weight and style. Other style attributes must match exactly. Style attributes are all attributes other than family and size-related attributes. Approximate matching for style considers :oblique and :italic as matches, but not as good a match as when the styles are equal.

Note that old-match must match desc.
