"Red Hat QXL controller"

In the "Red Hat QXL controller Properties" dialog:

- on the General tab, Manufacturer is "Red Hat, Inc."

- on the Driver tab, both the "Driver Provider" and the "Digital Signer"
  fields are "Red Hat, Inc."

This driver comes from "qxlwddm-0.1-12" (buildID=449635), in Brew.

In retrospect it looks like this driver was meant for Windows 8 only,
but it happened to install under, and work OK for, Windows 10 too.

Yes, it does. (Double-checked it with "confirm-SecureBootUEFI" in
PowerShell.)

I'm happy to try other driver versions. Hopefully Windows 10 will
actually see them as upgrading the currently installed driver. (Or
should I uninstall first?)

Thanks!
