[Fontconfig] Type Of “size” Property?

[Akira TAGOH]

The type specific getter/setter are still useful when you are sure
what type of values they are. fontconfig tries to convert a type of
value for setter as far as possible but for getter you better using
FcPatternGet and accessing through FcValue would be safe.
