There are two possible choices here: either pulling the lower bound of
the clamp down to `HitObject.Path.CalculatedDistance`, or pulling the
higher bound up to `minDistance`, if it happens to be larger than the
path's calculated distance.
Both options are a bit weird; pulling down can result in unsnapped
sliders when attempting to drag a slider's end when on a lower beat
divisor than was used to place the slider, and pulling up can result in
weird sliders wherein they get extended beyond their path's definition
with a weird linear section at the end without an anchor that is tangent
to the slider shape's end. I decided the first one was less weird, but
I'm open to discuss further.
The new carousel implementation was lacking some scroll related
behaviours. This makes sure that post-filter, the selection is
re-centered *unless* the user has scrolled away manually.
This matches the old carousel's behaviour. See
https://github.com/ppy/osu/pull/16647 for original implementation.
