The Eyedropper options bar now has Photoshop's Sample Size (Point Sample,
3 by 3 ... 101 by 101 Average), Sample (Current Layer, Current & Below,
All Layers, All Layers No Adjustments, Current & Below No Adjustments)
and Show Sampling Ring.
- engine: new `document.sampleColor {x, y, size, sampleLayer}`
(sample_cmds.rs). Averages the square centred on the pixel, clipped to
the canvas, alpha-weighted, in the document's colour model (Gray, Lab;
CMYK documents use their composite RGB, since the profile round trip
is not exact) and rounded to the document's bit depth.
- ui: eyedropper_ui.rs options bar; state.rs ToolOptions
eyedropper_size / eyedropper_sample / eyedropper_ring (serde). The
size is shared with the painting tools' Alt-click eyedropper, the
Curves / Color Picker eyedroppers and the Info panel readout.
- control: ui.set eyedropperSampleSize / eyedropperSample /
eyedropperRing; documented in control-protocol.md and the MCP schema.
- i18n: new strings in all 14 catalogs (plus the missing Russian hint
the tl! scan had not reached).
- scorecard: TOOL-1649-1.
