better_match

Determines if the style attributes of new_match are a closer match for this 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 this.

Parameters:

this	a `PangoFontDescription`
old_match	a `PangoFontDescription`, or null
new_match	a `PangoFontDescription`

Returns:

true if new_match is a better match
