We have to do this mapping dance since the keyframes were remapped but the Fmodifier evaluations are not.

So we undo the keyframe remapping and instead remap the evaluation time when drawing the curve itself. Afterward, we go back and redo the keyframe remapping so the controls are drawn properly.
