It's unclear to me what the following excerpt from the docstring
for the `fast-but-imprecise-scrolling' variable actually means:

> Note that this optimization can cause the portion of the buffer
> displayed after a scrolling operation to be somewhat inaccurate.

"somewhat inaccurate" is incredibly vague if you don't already
know what it means.

Does it mean that the position scrolled to might be further (or
less far) than it would have been otherwise?

Does it mean that the font-locking may be incomplete or incorrect?

Does it mean that the buffer text may appear corrupted?!

I certainly can't tell what it means. It would be good if that
text was clarified.
