Magnitude cap (px) applied to CONVERTED (line/page) deltas only, because a
page-mode event on a tall canvas or a line-mode driver reporting an outlier
line count would otherwise produce one absurd jump. Two Chromium notches: at
200 px a wheel zoom step is 0.95^2 (9.75% of distance) and an FOV step is
10 degrees — the largest single notch worth allowing. Firefox's ordinary
3-line notch (48 px) is nowhere near it.
