Full changelog

Brings the zoom rendering rework to main: fixes the high-zoom lag and the
edge flicker that the fix introduced, and bumps the version to 1.4.2.0.

Optimize canvas rendering via viewport cropping (57583cb) — crop to the
visible viewport and scale only that chunk, so zoom cost no longer grows
with zoom level (no more resizing a 1024² image to 16384² just to show a
corner). Also fixes the zoom-snaps-to-bottom-right bug and the
"Not Responding" hang from scroll event flooding.
Fix canvas edge flicker when zooming and panning (5a7f0bd) — zoom
repaints in a single synchronous pass, and the crop renders a small
overscan margin so scrolling never exposes un-painted canvas at the edges.
Update version info to 1.4.2.0 (afdf4e8).
