displayReferred property

Whether this material's color is display-referred (already final screen values) rather than scene-referred radiance.

A display-referred surface is drawn into its own layer past the tone curve and composited onto the resolved image, so its colors survive exactly. Captured widgets are the motivating case, and WidgetComponent turns it on for the material it owns. The surface is still depth-tested against the scene, but it receives no exposure, grading, tone mapping, fog, bloom or depth of field, and it is not ordered against translucent geometry.

A material that returns true must write display-encoded color premultiplied by alpha, not linear HDR.
