// A container that has a touch scrolling capability.
// description:
// ScrollableView is a subclass of View (=dojox.mobile.View).
// Unlike the base View class, ScrollableView's domNode always stays
// at the top of the screen and its height is "100%" of the screen.
// In this fixed domNode, containerNode scrolls. Browser's default
// scrolling behavior is disabled, and the scrolling machinery is
// re-implemented with JavaScript. Thus the user does not need to use the
// two-finger operation to scroll an inner DIV (containerNode).
// The main purpose of this widget is to realize fixed-positioned header
// and/or footer bars.
