For bringing a given view into the middle of the scroll view it's in, rather
than just into sight like focusing does.

A vertical ScrollView that extends into the bottom inset (like a navigation bar) adds
that much space after its contents, so the end can be scrolled out from under it.
It only did that when the view reached the very bottom of the screen, and then added
the whole inset. Since 58fa522d48 inset the content area of dialog screens on
screens over 600 dp, a phone like the S21 Ultra (617 dp wide) got a 1.7 dp inset,
which turned the extra space off. Add exactly the part of the view that lies in the
inset instead, and skip the bottom shadow in that case.

It stays for a second after the last activity, then fades out over half
a second. Any scrolling, touch, bob drag, or the mouse over the bob's
strip brings it back within a tenth of a second. It also shows briefly
when the view appears, so it's clear that it scrolls.

MSAA on tiler GPUs, the way we use it (we are not able to eliminate
load/store operations yet) can consume huge amounts of bandwidth, so let's be a
little bit careful.
