Defines interpolation to produce an even pace of change across the 活気／アニメーション.
This is only supported for values that define a linear numeric 範囲, and
for which some notion of "distance" between points can be calculated
(e.g. position, width, 高さ, etc.).
Interpolates from one value in the values 名簿（に載せる）／表（にあげる） to the next によれば a
time 機能（する）／行事 defined by a 立方（体）の Bezier spline. The points of the spline are
defined in the KeyTimes せいにする, and the 支配（する）／統制する points
for each interval are defined in the KeySplines せいにする.
