 * Surface Fog Effect — elevation-based ground-level fog.

 * Uses deck.gl's pixelUnprojectionMatrix to reconstruct the common-space
 * position of each fragment from the depth buffer.  The Z component of
 * that position corresponds to the fragment's real-world elevation
 * (scaled by distanceScales.unitsPerMeter).  Fog is applied to all
 * fragments whose elevation is below the user-configured height (meters),
 * with a smooth transition zone controlled by thickness (meters).
