No, *I* really do. And −1 for full-quoting and still failing to understand
what took me quite some time to get painted right:
scrollWidth != clientWidth + scrollLeft
scrollHeight != clientHeight + scrollTop

No, you MUST NOT use that because *inner dimensions* (i. e., that of the
element's *content*) computed this way will vary depending on the element's
scroll position, which is not measuring the inner dimensions *at all*.
