Lucy, you CANNOT arbitrarily call from a mirror driver into another display
driver. The other driver has already been initialized and assign a driver
object. You don't know that, and you don't want to pass YOUR driver object
to the other driver. A mirror driver is the WRONG solution for the problem
you need to solve.

What you need is a display filter driver, which is not a formally supported
concept. You need the operating system to load YOUR driver as the primary
driver, and they YOU load the original driver and filter the results. If
you do a little web searching, you might be able to find some documents
describing how to do this. It isn't easy. It's going to require a reboot
to install, and another to uninstall.
