It returns non-nil if the face attribute ATTRIBUTE is relative when it
has value VALUE.  "Relative" means that the value doesn't _override_
that attribute of an underlying face during face merging, but rather
_modifies_ it.

For most attributes the only value with that property is `unspecified';
some attributes have other relative values (for instance, with :height,
floating-point numbers are relative, as they specify a scale value
rather than an absolute size).
