We have this only for scrolling with the scroll bar: see
scroll-bar-adjust-thumb-portion. Implementing this for every possible
kind of scrolling would need changes to C code, I think, since
scrolling is actually performed by the display engine. Suggest to
file a feature-request bug report, and patches are welcome.
