Visibility floor of the gsplat fragment shaders: a fragment whose
(gain-aware, alpha-folded) shifted-Gaussian intensity falls below this is
discarded (intensity * max(uIntensity, 1) < 1e-4 in the visual shader,
intensity < 1e-4 in the pick shader). Interpolated into those discards
AND the vertex footprint math, so the two cannot disagree.
