Normally, we want to present focus ancestors, but for alt+tab, this is a major efficiency killer. We should set isPresentableFocusAncestor to False for this (like we do for the task list in older versions of Windows). However, this window is also used for the Task View, so we need to make sure we do report it in this case.

It seems the view is slightly different between these two cases. For the Task View, I see some groupings that I don't see with alt+tab. At worst, we might need ot detect whether the alt key is held down, but that's ugliness I'd prefer to avoid.
