IconAtlas

data class IconAtlas(val ids: List<String>, val interval: Double)

Icon atlas (parity with JS icon.atlas / Apple IconAtlasPaint: ordered ids and a data-value interval used to pick an index via floor(value / interval)).

For wind barbs the default ids are mapsgl:wind-barb-0 … mapsgl:wind-barb-100 in 5 kt steps and interval is the bucket width in m/s (JS: 5 * 0.5144444). Instanced GL barbs still draw procedurally in com.xweather.mapsgl.renderers.WindBarbInstancedRenderer; keep IconPaint.image consistent with these ids for any Mapbox symbol / tooling path.
