Review findings on region::plan:
- a drag at fit on a 4K or 5K display switched the window off (the whole-frame
draft shrinks, the preview-source cap does not): the window decision now
compares against the undrafted whole-frame render;
- overlays, soft proofing and windows refused for reading too far (a spot or Auto
Mask stroke) left the 1:1 view a canvas-sized upscale: those modes render the
whole frame at the size it is drawn, as before windows (a refusal is remembered
per photo, look and frame, and retried when any changes);
- the 3840 and 5120 preview sizes had become no-ops: a limit above the preview
source level is honoured;
- windows were limited to 8192 px frames: they now reach the photo's own pixels
(65536 px at most), so a medium-format photo is sharp at 1:1;
- a pinch out from a deep zoom asked for an ever wider window every frame: windows
already there are kept, magnified, until the gesture has been quiet.
The unused region::needed is gone.
