That was my original plan, to use the new API by default.

But then I decided to stay on the safe side, for compatibility reasons, 
continue using old API when you make the call using old API constants 
(CSIDL_*). For example, old API adds trailing path delimiter while the 
new API does not. Of course, users should ensure their trailing path 
delimiter themselves, but there could be other peculiarities which might 
affect the end users.

So for now, users of GetWindowsSpecialDir can make a conscious decision 
to upgrade to the default use of new API by using FOLDERID_* constants 
instead of CSIDL_* constants.
