Cross-thread handoff for CaptureAdjust. More...

Detailed Description

Cross-thread handoff for CaptureAdjust.

Not lock-free, and deliberately: a mutex taken only when the generation changed costs the render thread one relaxed load per frame in the common case, and reading the fields individually as atomics would let the renderer see half of one setting and half of the next – a visible colour flash while dragging two sliders.
