The dimming outside the crop box was four quads, each joining a side of the
photo to the matching side of the box. Aligned, that is the photo minus the
box; rotated, the quads cross themselves and each other, so wedges inside the
box were dimmed and wedges outside doubly dark, growing with the angle (the
reporter's -45° shows it best). The export was never affected: the overlay
alone was wrong.
The dimming is now `outside_crop_mesh`: the photo's rectangle minus the box,
as one mesh of four disjoint half-strips (outside edge i, inside edge i+1,
clipped to the photo). A flat or non-finite box dims nothing.
Tests: a coverage test over several box sizes and angles (every photo point
outside the box in exactly one triangle, none inside the box or outside the
photo), a degenerate-box test, and a headless pixel test at -45° (inside the
box the frame matches the 0° frame; the photo's corner is dimmed), which
failed on the old mesh.
egui's zoom_with_keyboard was left on, so at the end of every frame it took the
same keys as View ▸ Zoom In / Zoom Out / Zoom to Fit for its browser-style
interface zoom. On macOS the native menu bar got the keys first; on Windows and
Linux the whole UI scaled. theme::apply turns the option off for every context
(desktop, headless, tests).
Headless tests that pressed Cmd+Plus / Cmd+Minus to exercise the interface
zoom's viewport handling set the zoom factor directly; the CLI snapshot test
that did the same is dropped (the unit tests cover the mechanism). New
tests_zoom_keys.rs: the shortcuts step the photo zoom while the zoom factor
stays, and Ctrl+wheel over the photo zooms it in the Edit view.
A Custom white balance from a Lightroom catalog or XMP sidecar was taken as absolute Kelvin for every
raw. Raws LightCraft develops relative to their as-shot look (ARW, NEF, RW2, RAF, CR3, CR2, PEF; 6500 K
means as shot) then read a small tweak as a large blue shift: ΔE 22 against Lightroom's export on the
photos of issue #510.
The crs mapper now takes a `Target` (preset, rendered, raw with a measured illuminant, relative-WB raw)
instead of a bool. For relative-WB raws, and rendered files with only `Temperature`, a Kelvin value is
converted to the same mired shift from the packet's `AsShotTemperature` / `AsShotTint`. Without that
reference (Lightroom catalogs keep none for Custom photos) the photo stays As Shot and the import
report lists `Temperature, Tint` as not carried over. Import, sidecar read and catalog import decide
the target the same way through `lightcraft_catalog::relative_wb_format`.
Tests: shift from the issue's numbers (3650 → 3578 K lands at ~6275 K), the As Shot fallback with its
report entry, target selection per file, and the catalog mapper's Custom-WB case.
