The dialog's histogram fitted its tallest interior column to the plot, so one spike (a dark sky, a bright wall) flattened the midtones' hill to a few pixels. Camera Raw 16.1.1 scales linearly by the typical columns and lets a spike run off the top (measured on Photoshop 25.4: 49 px per 10 000 pixels in a 106 px plot, the 95th-percentile column at 14 546, the tallest at 21 600).
`rgb_histogram::Spikes`: `Fit` (the old behaviour, every other histogram keeps it) and `Clip` (the scale is at most 1.5 × the 95th-percentile column, taller columns clip at the top). The Camera Raw dialog's histogram uses `Clip`.
Test: `camera_raw_scale_lets_a_shadow_spike_run_off_the_top`.
Split out of #3816 at the reviewer's request.

`develop::tone` interpolates the camera curve logarithmically between knots, and a curve whose first knot sits at black (0, 0) made the first segment divide by log₂ 0: every value in it came out NaN, and `retone` (the open-time Shadows/Highlights preview) propagated it into the pixels. From a knot at black the segment is now linear, where log₂ has no value; the other segments are unchanged.
Test: `retone_lifts_shadows_with_a_curve_from_black` (finite output, shadows lifted, highlights kept) fails without the fix.

The shortcut pass runs before the panels are drawn, and its crop/polygon
branch consumed Esc and Enter even while an egui popup of the options bar
was open (the Ratio list, the overlay and gear menus): Esc cancelled the
crop and left the list open, Enter committed the crop beneath it. Skip the
branch while `egui::Popup::is_any_open` (kept in memory from the last
frame; `ctx.any_popup_open` only sees the current pass).

The stroke preview was white at a quarter opacity, invisible on white
and faint elsewhere. Photoshop shows the area to heal in half-opaque
dark grey; the trail now does too. Other retouch trails are unchanged.
Test: drag_preview_canvas::the_spot_healing_trail_is_a_dark_half_opaque_tint
drags the real canvas offscreen on white and mid-grey and checks the
trail darkens the pixels to 40-60 %; it fails with the old colour.

Sampler points are pixel indices, but rotate_arbitrary mapped them as the
pixel's top-left corner while the warp moves pixels by their centres, so
after a turn a point sat one pixel off its pixel, or fell off the canvas
(a corner point at 90° or 180°). Map the pixel centre, as #6720 does for
flips and right-angle turns; the turned Crop shares this map.

rotate_arbitrary read `angle` as f32. rotated_crop sizes its canvas with
rotated_size at f64 and passes the angle through JSON; near a whole-pixel
ceil boundary the f32 angle grew the canvas 1 px more (1000x1000 at
0.11470651449337071: 1003 instead of 1002), shifting the crop by 1 px.

A fill layer from a PSD keeps its stored pixels as a fill cache that covers
only the old canvas. Canvas Size, an extending Crop and Reveal All translated
that cache but kept it, so the added area of the fill layer stayed
transparent. Drop the fill caches whenever the canvas grows, so the fill
re-renders from its model over the whole canvas, as Photoshop does (Free
Transform and Perspective Crop already drop it).

The + button in Window › Tool Presets stored the whole ToolOptions struct, so choosing
the preset later wrote every other tool's options back (e.g. Crop's Delete Cropped
Pixels). Reset Tool's per-tool field lists become `option_keys`, which the + button now
uses to store only the tool's own options. Brush/Pencil Clear, the Eraser's mode, the
Remove tool's options and Content-Aware Move's Transform On Drop join their tools' lists,
and a test checks that every option belongs to a tool.

The copies were made with Document::new and kept the mode but not the
duotone inks, so a Duotone scan came out as plain gray. Copy them, and
grey the command out for Indexed Color documents, as Photoshop does.

The rotation and instance-log tests in logging.rs, and two app_dirs migration-lock tests, drop a
flock and check straight away that it is free. A child that another test spawns at that moment
holds a copy of every open descriptor until its exec, the lock included, so the check sometimes
saw it still held (about 6 failures in 15 runs of the app's test binary). Tests that spawn
children (the portal mock's dbus-daemon, the display-profile helper test) now hold CHILD_SPAWNS
for reading while they spawn, and the lock tests hold it for writing.
The portal mock made its message stream inside its thread; a stream only gets messages that
arrive after it exists, so a SaveFile sent before the thread got going was lost and the test
waited forever (about 1 run in 25). The stream is now made before the thread starts.
