* perf: reuse large buffers so a pinned glibc trim threshold costs no speed (#10479)
With MALLOC_TRIM_THRESHOLD_ set (#8743), glibc maps every allocation over
128 KiB fresh, so tiles, compositor bands and filter scratch were page-faulted
in on every call: viewport compose 3.6x slower, Gaussian Blur up to 1.8x,
.pcraft save 2.4x.
- photocraft_raster::scratch: a process-wide, capped pool of large Vec
buffers (u8/u16/f32/[f32; 4]). A miss drops the oldest buffers worth its
size down to a 256 MiB floor, so peak memory stays near glibc's defaults.
The engine releases the pool after any command that closes a document,
Headless::close does too, and an idle thread releases it after 2 s unused.
- Tiles, compose Buffer/masks/bands, algo Image and the blur paths, engine
adjustment/filter scratch, GPU tile upload and io import buffers go through
the pool.
- .pcraft save reuses one zstd FrameCompressor per worker (byte-identical).
- interactive_bench reports minor page faults per run.
36 MP, trim threshold set vs glibc defaults: viewport 5.6 vs 6.1 ms (was
22.7), Blur r4 445 vs 437 ms (was 852), Curves CPU proxy 35.0 vs 35.7 ms
(was 50), flatten 146 vs 147 ms (was 237), save .pcraft 251 vs 230 ms (was
545). RSS after closing a 5400x7200 document: 21 MB with trim set.
* fix: corpus tests build again; return remaining pooled buffers (#10479 review)
- Corpus-gated io tests and the Photoshop-oracle test moved `.px` out of a
`Buffer`, which now implements `Drop` (E0509 with `--features corpus`):
use `into_px()`.
- io: masks, the merged image, extra channels, smart-filter masks,
smart-object pixels and patterns give their `interleave` buffers back to
the scratch pool after writing them.
- compose: recycle the mask values of a pass-through group, `effect_shape`
and both `split_parts` callers.
- Styled Free Transform preview copies each band out instead of moving it,
so the band returns to the pool.
- interactive_bench: the fault count covers each whole run, untimed setup
included; say so.

Reverts #8039 ("Compose: Extend Softer outer glows past Size (#7899)"),
which added a range-scaled fading tail beyond Size to Softer outer glows,
on the CPU compositor and the GPU one alike, and widened the effect
margin by it.
The reference application, measured: Outer Glow, Softer, Size 60,
Range 50 % (and 100 % alike), white, Normal, Opacity 100 %, Spread 0,
Noise 0, on an opaque white shape over black (240 x 40 document, shape
over the left 100 px, full height, sampled at row 20): the glow reads 4
at 50 px from the edge, 1 at 54, and 0 from 56 to 70 px. It reaches zero
just before Size; there is no tail beyond it.
The reverted code (the two-box tent) gives, in that setup, 8-bit levels
4, 1, 0, 0, 0 at 50/54/56/60/70 px for Range 50 % (unrounded 3.56,
1.20, 0.49, 0, 0) and 2, 1, 0, 0, 0 for Range 100 % (1.78, 0.60, 0.25,
0, 0); #8039's tail lifted 56-62 px above zero. So the revert stays as
is, CPU and GPU unchanged from before #8039.
Conflicts were formatting-only (later rustfmt of #8039's lines) in
compose effects.rs, effects/paint.rs and gpu fx/builders.rs; resolved to
the pre-#8039 code. The GlowSource/GlowTechnique imports a later commit
kept in gpu fx/tests.rs for #8039's test go with the test.
New test softer_outer_glow_fades_out_before_its_size renders that
document through the CPU compositor at Range 50 % and 100 % and checks
50 and 54 px within 2 levels and 56, 60 and 70 px at exactly 0.

Port behavior and regression coverage into current modules; preserve current upstream behavior.
Reconcile captured Pen and Freeform targets with current resumed-subpath, Type Path, Path Operation and draft recovery behavior. Valid source-owned tab switches commit to captured original target; invalid snapshots cancel with a diagnostic; refused commits retain draft and suppress automatic retries. Preserve current Saved(index) API and hidden-work-path protections, register all new ownership/gesture tests and add original-target tab-switch/deleted-target cases. Includes verified compile/API corrections from prior checkpoints.
Port behavior and regression coverage into current modules; preserve current upstream behavior.
Current modular compositors already implement spatial Dissolve for adjustments and finished effects. Preserve equivalent implementations and newer Fill/HDR behavior, append approved missing CPU/GPU regression coverage.
Port behavior and regression coverage into current modules; preserve current upstream behavior.
Use shared zoom-corrected brush resize and HUD while preserving immediate press ownership and anchored outline when hover is absent. Keep original resize regressions. Fix duplicate identical Dissolve test registration and missing test-only UnicodeString import reported by 94-head check.
Port behavior and regression coverage into current modules; preserve current upstream behavior.
Current CPU and GPU already implement binary clipped Dissolve at document coordinates. Preserve current equivalent implementation and stronger negative-origin/depth regression; retain original named regression and added GPU parity coverage.

Integrated independent exact shape paints and atomic pattern clipboard snapshots into current modules, preserving current soft-mask coverage, shape cache keys and gradient stop caps. Shared bounded COW pattern sampling now retains minification filtering; shapes/clipboards resolve lazy catalog entries to full pixels. Preserved CPU/GPU/depth/model regression matrices; also corrected missing glow-test enum imports found by the 80-head check.

Port behavior and regression coverage into current modules; preserve current upstream behavior.
Combine Fill-aware adjustment blending with stable HDR coverage and add cross-feature CPU/GPU regression matrix.
Main now carries #9031 (Halftone) and #8923; this branch keeps only what it adds on top: the guard for a setting beside a Gallery stack's effect list, its test, and the PSD open warning for patterns that paint nothing.
Main reorganised the source tree (command modules under engine/src/cmd, tools and dialogs under ui-egui/src, large files split into modules, inline test modules moved to their own files). This branch's changes to the moved and split files are ported to their new locations.
The per-pixel reference mixed a type layer's fully covering pixel through
the type gamma round trip, which leaves white one float step short of no
ink (1 - 0.99999994). Vivid Light jumps exactly there (a source at full
brightness gives full brightness, anything below over no brightness gives
none), so a white glyph clipped onto a Vivid Light group over magenta
became full magenta in the reference, while the compositor (which keeps
covered pixels exact, like normal_gamma) gave no ink. The reference now
treats a fully covering source like the compositor and the identity it
is: the source's ink exactly.
Adds a named regression test with the shrunk document and a neighbour
test over Vivid/Linear/Pin Light, Hard Mix, Color Dodge/Burn, Normal,
Multiply and Screen with type or pixels clipped, plus the proptest seed.

A Pass Through group composites its children straight into the
backdrop, so an Invert inside it changed the layer beneath even when
the group had Blend If. Photoshop renders such a group isolated, as it
does below 100% Fill: the backdrop stays (64,128,192) under a group
holding an Invert with Red Underlying white at 110. The CPU and GPU
pass-through shortcuts are now skipped for a group with Blend If.

Blend If on an adjustment layer judged This Layer by the composite after
Opacity and the mask had mixed the result into the backdrop. Photoshop
judges the adjustment's result itself: Invert at 40% over (64,128,192)
with Red This Layer black 150 keeps the effect, (115,128,140), as
Invert's red 191 passes 150. The CPU and the GPU now apply the
adjustment to the backdrop and judge that.

Gray was Rec. 601 luma, unrounded, so mixed 8-bit colours near a hard
Gray point landed on the wrong side: (123,126,151) read 127.95 and was
hidden by a black point at 128. Photoshop's Gray, measured on pure
channels at three cutoffs, is (30R + 59G + 11B) / 100 rounded half down
on whole levels; it keeps both of the reporter's colours.

* chore: resolve SonarCloud maintainability issues
* fix: format imports and fix effect_entry argument type
* fix: restore test closure and wildcard import that broke compilation
* refactor: split composite_to_surface to reduce cognitive complexity
A hard Blend If point at level c sits on Photoshop's 16-bit step
round(c * 32768 / 255), inclusive for black and white points (measured
at 1, 64, 128 and 200). blend_if_level snapped only within 1e-4 of a
whole level, so RGB16 32895 (level 128's step) read 127.996 and was
hidden by a black point at 128. A value on its nearest level's step is
now that level, on the CPU and the GPU; 8-bit levels are unchanged.
