Раньше BounceLight собирал только отраженный свет от предыдущего прохода, результаты проходов суммировались. Теперь собирает сразу от суммы всех предыдущих. Поэтому делюксмапу больше не нужно накапливать, она считается один раз на последнем проходе.
Умножение на альбедо вынесено в CollectLight, чтобы не считать его каждый раз в BounceLight.
