betterMatch

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 null, 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 %PANGO_STYLE_OBLIQUE and %PANGO_STYLE_ITALIC as matches, but not as good a match as when the styles are equal.

Note that @old_match must match @desc.
