OptionalenabledWhether the pass starts enabled; see Pass3D#enabled
OptionalintensityStrength of the glow added back onto the frame
OptionallevelsNumber of blur levels; each is half the size of the last and doubles the glow's reach
Rounded to a whole number, at least 1. Fixed at construction.
OptionalradiusHow much each coarser level blends into the finer one, 0 to 1
0 keeps only the finest level, a tight halo. 1 replaces each level with the coarser one,
the widest and softest haze.
OptionalresolutionTexels per logical pixel for the largest blur level, like a pixi filter's resolution
A glow has no fine detail, so a fraction is the usual choice. Fixed at construction.
OptionalstageWhether the effect reads the scene as light, before the tone curve, or the picture as it will show, after it
Each effect class picks the right one by default, so set it only to move one instance, such as a tint meant for the light rather than the picture. See PostEffect#stage.
OptionalthresholdBrightness above which a pixel blooms, measured on its brightest channel
A pixel blooms with the brightness it has above the threshold, eased in from half the
threshold, so the cut-off is soft. At the default stage it's measured before the tone curve, so 1 blooms mostly what is
brighter than white.
