+Image navigation is also available directly as the UI command `view.navigate`, with
+`{zoom?: "fit" | "fill" | {"percent": number}, pan?: [x, y]}`. Percentage zoom accepts fractional
+values greater than 0 and at most 800; pan is the normalized image centre, with coordinates from 0 to 1.
+Pinching keeps the image point under the pointer steady and zooms between Fit and 800%; two-finger
+scrolling pans in both axes and respects the operating system's scrolling direction and momentum.
+These gestures work in Detail (including editing tools and full-screen preview), Compare and Reference
+views, and only apply over their image areas. Panning stops at the image edges.
