/**
* The scroll window widget scrolls an arbitrary child window.
* Use the scroll window when parts of the user interface itself
* need to be scrolled, for example when applications need to run
* on small screens. The scroll window observes some layout hints of
* its content-window; it observes LAYOUT_FIX_WIDTH, LAYOUT_FIX_HEIGHT
* at all times. The hints LAYOUT_FILL_X, LAYOUT_LEFT, LAYOUT_RIGHT,
* LAYOUT_CENTER_X, as well as LAYOUT_FILL_Y, LAYOUT_TOP, LAYOUT_BOTTOM,
* LAYOUT_CENTER_Y are however only interpreted if the content size
* is smaller than the viewport size, because if the content size is
* larger than the viewport size, then content must be scrolled.
* Note that this means that the content window's position is not
* necessarily equal to the scroll position of the scroll window!
