class SpzDecodeOptions(val skipRotations: Boolean = false, val skipOpacities: Boolean = false, val skipSphericalHarmonics: Boolean = false)
Per-attribute skip flags for SpzGaussianLoader. Each skip* flag short-circuits the corresponding decode loop (the cursor still advances over the bytes when later sections follow), and the payload field is left empty/null. Use ROUND_SPLAT when the renderer only needs centres + scales + rgba — the rotation, opacity, and SH decodes are by far the most expensive operations in the parser.
