Hi,
This patch adds implementation for the IFilterMapper interface.
Nice. I have few comments (see below).
However filters registered with this interface require
some work in
devenum to
be seen from application. This will be done when time permits.
Ok. I had assumed devenum was complete, but obviously not. Does it spit out
any fixme's?

You can remove the SUCCEEDED(hrSub) completely here.

Indentation messed up a bit here and many other places.

Please choose one style of bracket placement and stick to it (this occurs in
a few places too).
Other than these things, it looks fine.
