area_lighting

Shades every area light in the scene: a rectangle, disc or tube is integrated over its surface rather than treated as a point, so the highlight has the light's shape.

Bindings

name	kind
scene_color	texture2d
scene_depth	texture_depth
scene_normal	texture2d
scene_material	texture2d (sample: uint)
frame_cam	buffer, read vec4<f32>
area_light_params	buffer, read vec4<f32>
area_light_records	buffer, read vec4<f32>
area_out	storage2d (rgba16f)

area_out holds linear light, which an area light's contribution can carry past 1.0 — an 8-bit target would clamp it.
