Just to double-check, is it still shown as soon as the user moves the mouse?

I'm not sure that this is the right behavior.  I think that most developers run
local builds in non-logged-in mode; it might be strange if the cursor is always
hidden when they do that.  I think we really only want to hide it when we're
displaying the login screen or OOBE.

Yes, CompoundEventFilter::SetCursorVisibilityOnEvent will show the cursor as
soon as the user moves the mouse.
That's a good point. I changed the code to hide cursor only when displaying the
login screen if developer runs local builds on desktop.
