With General › Zoom with Mouse Wheel, each wheel notch's zoom was applied on the frame it arrived, so the view jumped a step per notch while scrolling glides over a few frames. A mouse wheel's notches now glide in (what is left shrinks by e every 50 ms), ending at the same zoom; a trackpad's fine steps still apply at once.
