Dylan M. Taylor d318583867 fix(render): optimize table styles, chart lookups, line trimming, and canvas limits (#1288)
* fix(render): optimize table styles, chart lookups, line trimming, and canvas limits

* fix(render): give outer-shadow passes their own traversal budget

A shadowed group's silhouette pass shared the 100,000-visit limit with normal drawing, so a group with many children could use it up before anything visible was drawn.

* perf(render): resolve a table's style once per draw

5fadda5ecf chore: resolve SonarCloud maintainability issues (#1255)
* chore: resolve SonarCloud maintainability issues

* fix: address shellcheck SC2059 and fix generic cast ambiguity

* style: apply rustfmt formatting

* fix: restore compile and behaviour in Sonar refactors

- fonts: char::is_alphanumeric takes &self, so filter needs a closure
- h264: keep the mvd accumulator as i32 (prefix is usize)
- model: annotate the non-stacked range accumulators as f64
- engine: chart.options still clears the raw chart XML for upDownBars
  and quartiles; smartart goes back to the glob import (cmd! macro)
- web: keep the original viewport meta (behaviour change)

Nikita RakitinandCursor d04df05249 Export: record slide resolution in PNG and JPEG pictures
A default export is 2 pixels per point. Without a resolution, Preview
treats those pixels as 72 dpi and the picture opens at twice the slide's
size. PNG pHYs and JPEG JFIF density now say scale times 72, so the
default is 144 dpi. Screenshots stay untagged.

Nikita RakitinandCursor 201ab63c48 Render: cap RGBA conversion and bound the failed-image cache (#402)
decode_at accepted up to 400 million pixels and then called to_rgba8, which
the decoder's allocation limit doesn't cover (a grey image converts to four
times its decoded size), and every picture that failed to decode was kept,
bytes and all, for the life of the process.

- Raster decodes check the RGBA size (512 MiB cap) from the header before
  decoding and again before the conversion.
- The failed-source cache keeps at most 256 entries and 64 MiB of encoded
  bytes, oldest forgotten first; a larger failed input isn't kept, and a hit
  must be the same Arc.

Brandon ThomasandClaude Opus 5.5 675d20417e Pictures: black and white, inverted alpha, and PowerPoint's grey weights
- a:biLevel (Color > Black and White) was ignored. It is now read, written
  and drawn: white where the luminance reaches the threshold, else black
  (observed thresholds at 30/50/70% on colour swatches).
- a:alphaInv was ignored; an opaque picture with it is invisible in
  PowerPoint. Now read, written and drawn.
- Grayscale, duotone and saturation weighed channels 0.299/0.587/0.114;
  PowerPoint's export greys pure red to 54 and green to 182: Rec. 709
  weights (0.2126/0.7152/0.0722).

Wild synthetic set: recolour slide 7.60 -> 1.15, picture corrections
13.36 -> 7.36.

Brandon ThomasandClaude Opus 5.5 bf877411fb Render: picture brightness with contrast as PowerPoint combines them
Brightness was added after the contrast stretch. Measured on PowerPoint's
export of grey ramps (5 x 5 grid of -80..80% brightness and contrast):
contrast scales about mid-grey (x(1+c) below zero, /(1-c) above) and
brightness adds b * 255 scaled by (1 + cf) / 2, half before the stretch
and half after; +40% brightness with +40% contrast maps black to 54, not
17. DeckCraft now matches the 25 ramps within 5 grey levels.

Wild synthetic set: brightness/contrast grid 15.93 -> 13.36, recolour
slide 8.74 -> 7.60.

Brandon ThomasandClaude Opus 5.5 3b04dd14be Render: pictures with opposite corrections no longer share decoded pixels
The decoded-picture cache keyed adjustments with an xor-multiply mix in
which brightness b, contrast c and -b, -c collide (the sign bits cancel),
so of two copies of a picture, one +40% bright and contrast and one -40%,
both showed whichever was decoded first. The key is now a real hash.

Wild synthetic set: brightness/contrast grid 27.86 -> 15.93.

Brandon ThomasandClaude Opus 5.5 4773e4ee0f Render: tiled pictures take their size from the resolution they record
A tiled picture fill (including a blipFill with neither stretch nor tile,
which PowerPoint tiles) assumed 96 dpi. PowerPoint sizes a picture by the
resolution its file records: a 32 px tile saved at 90 dpi is 25.6 pt, not
24. The PNG pHYs chunk and JPEG JFIF density are now read (rounded to
whole dpi) and scale the tile.

Corpus lo/tdf128596 (tiled checkmark texture): 8.79 -> 0.52 mean diff
(it had drifted from 7.36 when tiles started snapping to whole pixels).

Brandon ThomasandClaude Opus 5.5 c2b622a797 Render: tiled picture fills flip, align and size like PowerPoint's
- flip x/y/xy (every other tile mirrored) was ignored: tiles now repeat
  reflected across the flip axes.
- algn was ignored: the first tile now sits on the corner, edge middle or
  centre of the box it names, before the tx/ty offset.
- The tile size came from the decoded (possibly downsampled) bitmap; it is
  now the picture's own pixel size (96 dpi) times sx/sy, rounded to whole
  output pixels as PowerPoint draws it.
- A scale of zero or less drew tiles at 100%; PowerPoint draws nothing.
- Tiles are one repeating image paint instead of one draw per tile (no
  200-tile cap, constant cost).

Wild synthetic set: tiled background flipped/aligned 82.92 -> 1.80, tile
variants 51.15 -> 8.82.

Brandon ThomasandClaude Opus 5.5 4d13652f0f Pictures: duotone recolours, and layout/slide colour map overrides apply (#269)
Theme background pictures (Office 2007-era themes such as Treck) carry an
a:duotone recolour in phClr; DeckCraft read it but drew the picture
unchanged, so those backgrounds came out grey. The painter now resolves the
duotone's colours against the slide's colours and placeholder colour, and
the decoded-image cache applies them (luminance picks a colour between dark
and light) and keys on them.

Layouts and slides can replace the master's colour map
(p:clrMapOvr/a:overrideClrMapping, e.g. dark section layouts mapping bg1 to
dk1). They were read as the master's map; now Layout and Slide carry an
optional colour map, resolve::Ctx uses slide > layout > master, and the
writer keeps them.

3985d768e6 feat(pictures): animated GIFs play, with pause (media.gifPlay) (#39)
* feat(pictures): animated GIFs play, with pause (media.gifPlay)

GIF pictures used to show only their first frame. The renderer now decodes every frame (cached, capped at 256 MB and 1024 px a side) and draws the frame for each GIF's play time, passed in RenderOpts::gif_times; exports and thumbnails pass none and keep frame 1. The editor canvas and the slide show redraw only when a GIF reaches its next frame. A corner button on hover (or selection) pauses and resumes a GIF from the same frame, through the new media.gifPlay command.

* Animated GIFs: cap frames (1000), canvas (4096²), per-GIF (64 MB) and cache (192 MB) memory

A few MB of hostile GIF could decode to millions of tiny frames or a 100 Mpx canvas per frame,
and eight cached GIFs could hold 2 GB.
