I'm sure I saw it somewhere in Wine and I liked it. AFAICS there are no
object to interface cast wrappers in msxml3 (except for dispex.c, which
is copied from mshtml), so I thought I could introduce it here.

I just feel that it's better to have a wrapper to avoid explicit casts
in the code and have vtbl logic separated from other code. I usually use
macros, but I know you don't like it, so I used an inline function here.

I will resend these patches without the wrapper.
