Conflicts: crates/engine/src/tests_merge.rs (#1123's test landed where this branch's is; both kept),
docs/parity-checklist.md (the LR-MERGE-HDR row: both notes) and docs/whats-new.md (both entries).

A drag tick requested the loupe's draft and the frame ended; the draft,
done in 1.5-3 ms on the GPU, was picked up at the start of the next frame,
a frame after the slider moved. Now, in a drag, the loupe waits up to 40 %
of a frame for its draft when the last loupe render took well under that
(not with a render offload, nor zoomed in, where what changes on screen is
the window's draft). A CPU render, which would only make the frame late, is
not waited for.
JobPool::wait waits for the next finished job, which try_recv then hands
out; Renderer::poll's collection of finished jobs is split out so the wait
can turn the draft into the texture.

The semibold family had a semibold Inter but, for other scripts, the same
regular craft-fonts faces as regular text, so a heading or the chosen tab
in Arabic was drawn at regular weight beside bold Latin.
A fallback face with a weight axis (today Noto Sans Arabic, 100 to 900)
is now registered a second time for the semibold family at weight 600,
through epaint's FontTweak::coords. The bytes are borrowed from the
embedded font, not copied. Faces with one fixed weight, regular and
monospace text, the order of fallbacks and Latin are unchanged.

Merged HDR DNGs lost the camera's embedded lens correction: load_frame strips the lens opcodes from each
source (frames are merged uncorrected) and write_linear_dng wrote no OpcodeList3, so Optics ▸ Enable Lens
Corrections did nothing on the result (Sony ILCE-7M3/7RM4A, Panasonic/Leica, DNGs with their own opcodes).
Each raw frame now keeps the lens corrections it applies (the DNG 1.6 skip rule already applied),
re-expressed for the default crop develop keeps by the new Opcode::cropped: the centre moves into the crop
and coefficients are rescaled for the crop's farthest corner. HdrResult carries the reference frame's and the
DNG writes them as its OpcodeList3. Frames turned before merging (mixed orientations) and panoramas carry none.
Tests: cropped corrections give the crop of the corrected whole (WarpRectilinear, WarpRectilinear2 with and
without reciprocal, FixVignetteRadial); an HDR merge of cropped, corrected brackets, upright and vertical, gives
the same profile correction as its reference photo (fails without the fix). Real brackets not measured yet.
