Well, I'd like to change my stand again. I still think that we should
provide a way to check whether some descriptors are specified.

In the 'override' system, unspecified descriptors should inherit the
value from the corresponding descriptor of style it overrides instead
of the initial value. If the system is 'override' and the initial
value is returned for unspecified descriptors, it is unable to know
whether a descriptor is unspecified, or specified with the initial
value occasionally. Or do you want to return the inherited value
directly? I don't think it's a good idea since it requires to parse
another style to generate the values.

Consequently, my suggestion is that, if a descriptor is unspecified,
for 'system' descriptor, yes, the initial value can be returned, while
for other descriptors, null should be returned.
