This is a  mouthful. Is the CreateAndActivateMetro some pattern for creating
metro / touch infobars?

Most info bars just have a static 'Create()'. This one has a significant
side-effect that it also activates metro mode Chrome. And it was originally
called just 'Activate()' but didn't have the constructory feel in review at
