convertFromScrollbarToContainingView and friends should be in ScrollView (but still overridable) This is breaking Chromium's build because PopupMenuChromium inherits from ScrollView, but these functions are pure virtual in it. I could put it directly in PopupMenuChromium, but that seems a bit silly since the functions are fairly generic.
