in the extrapolated area.

last keyframes uniformly, along the
existing trajectory.
Repeat Duplicates the curve, applying it again
and again.
Ping Pong Copies the curve and repeats it,
alternating forward and backward.
Progressive Extends the curve by repeating the
existing shape of the curve, but rather
than returning to the exact same values,
it begins again from the existing end
value.
