Saves having this defined in 20+ places. If we ever make any changes to
shear, it's 100% going to need to be applied to every usage (there will
never be a case of multiple different shears in the game).
Also fixes a mismatching definition in `ShearedNub`.
Important to make "select/deselect all" operations work on all columns
simultaneously, even if they're offscreen. Unfortunately by the nature
of how the existing selection animation works, it is hard-tied to the
update loop, so we need to compensate.
It was causing selection/deselection of all mods to work improperly if a
select/deselect all operation was requested before the panel was
scrolled into view.
In general the schedule was an over-optimisation - the game-global set
of available mods shouldn't be changing so often as to warrant such an
aggressive debounce.
