-// IMPORTANT NOTES ABOUT SCROLLBARS
-//
-// WebKit uses scrollbars in two ways.  The first way is as a scroll control
-// for a ScrollView.  This scrollbar sits inside the ScrollView's rect and
-// modifies its scrollOffset.  Because it is inside the ScrollView's rect, it
-// is a child of the ScrollView, but because it is not really part of the
-// scrollView's content, it doesn't move as the scrollOffset changes.
-//
-// The second use is as a scroll control for things other than a ScrollView,
-// e.g. a <select>.  A <select> is not a ScrollView, so the scrollbar is not a
-// child of it -- instead, it is a child of the ScrollView representing the
-// frame in which the <select> (and the scrollbar) are located.  In this case,
-// the scrollbar IS part of the ScrollView's content, and it moves when the
-// scrollOffset changes.
-//
-// ScrollViewWin distinguishes these two cases in its convertChildToSelf and
-// convertSelfToChild methods, which are used when converting coordinates
-// between the ScrollBar's coordinate system and that of the native window.
