NO!

This class represents a generic shorthand, not a dumping ground for random extra
field to handle special cases.

Also, booleans are usually frowned upon as they make the code less readable.

Done.

Also, my patch doesn't even apply anymore, since StylePropertyShorthand.h is
gone and is now auto-generated. :)
