Orkuncakilkaya ae52e9c4da feat(render3d): anti-aliasing that exists, and a lens for the viewfinder
The shipping default had NO anti-aliasing at all: the temporal resolve was removed, the
setting's first option went on saying "Temporal", and MSAA defaults to one sample, so
every machine without DLSS drew grass and needle cards with nothing smoothing an edge.

FXAA in the sharpen pass, which already reads the neighbourhood and runs last on the LDR
image. No history, so it cannot drag or smear a reflection. 25.5% less single-pixel
staircase on edge pixels.

The trap, recorded because it inverted the result: the unsharp delta must be computed
from the RAW image and only then applied to the anti-aliased colour. Centre from FXAA and
neighbours from the raw texture measures half smoothing and half signal, so the mask
sharpens precisely what FXAA softened - 29% WORSE than no anti-aliasing at all.

Depth of field for the photo mode: a disc whose radius is the circle of confusion,
normalised by focus distance so a landscape shot is not a macro, with taps rejected
unless they are at least as out of focus as the pixel they blur into - which is what
stops a sharp foreground haloing into a blurred background. Between the scene and the
bloom, so a blurred highlight still blooms. Skipped whole when the aperture is shut.

400 frames in ordinary play: GL 7.1 s, VK 7.2 s - the lens does not draw there.
