bherbruckandClaude Opus 5.5 6f115ad740 Optional supersampling (SSAA) for the viewport, adaptive and capped to the texture limit (#1288) (#1321)
* Optional supersampling (SSAA) for the viewport, adaptive and within the texture limit (#1288)

Preferences ▸ Graphics ▸ Supersampling: Off (default), 1.5× or 2×. The frame is drawn into
textures of the viewport's own kind (format, depth/stencil, MSAA) at that multiple of its pixels,
over transparent black, then filtered down into the viewport with four bilinear taps (the exact
2 × 2 box at 2×) and composited premultiplied over the background. Lines keep their on-screen
width; silhouettes and edges come out smoother.

Adaptive (on by default): the view is drawn at full speed while the camera moves and
supersampled once it has held still for a quarter of a second.

The supersampled size stays within the device's largest texture side (#869) and a 384 MiB
budget for colour and depth (MSAA samples included); under 1.25× is not worth it and the frame
is drawn as usual.

Labels in en/de/ja/ko/zh; `ui.prefs` `supersampling` and `supersampling_adaptive`.

* Supersampling: factor and adaptive on one row; Off reads Off (1×)

The Graphics page grew past the colour vision menu in the preferences scenario, and a second
Off on the page took its click.
