#1123 gives HDR and panorama merges of raws without colour matrices the colour they open with, but writes
ColorMatrix1 from the forward matrix, so the as-shot white the DNG declares lands wherever the fitted look and the
generic camera model take it. On real ILCE-7M3 brackets the HDRs opened at As Shot 6113–7307 K / +115 (Duv +0.038)
where the ARWs show 3932–5268 K / +7, and any white-balance edit turned them green (CIEDE2000 11–13 against the ARW
at the same Temp/Tint). The render at As Shot was right (0.4–0.8).
The colour matrices now declare the white balance the source shows, decided by files::WbScaleOf (new dng_white):
the camera's measured matrices when they give the source's scale (lightcraft_raw::spectral; the DNG then reads every
white as the source does), else a matrix under which the as-shot neutral is the white the scale shows (Sony's
presets' reading, 6500 K / 0 on the relative scale, the file's own white otherwise). Forward matrix and neutral are
unchanged, so is the render at As Shot.
Measured on the same brackets with this change on a fork build: As Shot 4813 / 5268 / 3932 K, +8 / +8 / +7 as the
ARWs (declared white Duv +0.003); same Temp/Tint within CIEDE2000 0.8–1.7 of the ARW for most changes, about 5 for
the largest (5268 → 3200 K, 3932 → 6500 K: the ARW adapts its look with Bradford, the DNG rebalances in camera space).
Tests: a merged DNG shows its source's As Shot on all four scales (measured matrices, presets, relative, own); with a
look that tints white the DNG declares the shown white, gives the measured model's multipliers at other whites and
renders at As Shot as the source does. Both fail on main (ILCE-7M3 case: (7342, 115) for (5268, 8)).

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.
