Also, there's nothing windowzy about this _win.cc file that I can see? Any
platform specific differences seem like they can be handled in your UIManager
class.

The current design is that only Windows Chrome will use its own UI for
notifications, and that Mac/Linux will go to a 3rd party presenter library -- so
really only Windows has a UI manager at all.  But from recent design feedback I
will be changing this so that Chrome does the UI on all platforms, in which case
it will get refactored like you say.

Right now, the instance will always be NULL in chrome afaict.

If this is the only callsite for methods on the uimanager class, it may be
better to comment this out for now and to not submit the UIManager.h file with
this CL.
