I see now.

Before this post I did a search in Emacs info and can not find the
answer not even scrollBarWidth. Is there a complete list of X resource
options hidden somewhere?

Also is there any reason to make the width of scroll-bar take up even
character width? Because the gap is not pretty and very noticeable.
