Lisp_Windows without worrying about those references becoming
dangling references when the scroll bar is destroyed.

The window-system-independent portion of Emacs just refers to
scroll bars via their windows, and never looks inside the scroll bar
representation; it always uses hook functions to do all the
scroll bar manipulation it needs.

window's scroll bar, or is nil if the window doesn't have a
scroll bar.

are free for use by the scroll bar implementation in any way it sees
fit. They are marked by the garbage collector. */
