InternalFilamentApi
@RequiresOptIn(level = RequiresOptIn.Level.ERROR, message = "Raw native handle: an implementation detail of filament-kmp, not supported API.")
@Target(allowedTargets = [AnnotationTarget.PROPERTY, AnnotationTarget.FUNCTION, AnnotationTarget.CONSTRUCTOR, AnnotationTarget.CLASS] )
Marks a raw native handle that filament-kmp's own modules share across module boundaries.
These members expose backend pointers directly: writing one, or reading one after the owning object has been destroyed, crashes the process. They are not part of the supported API and may change or disappear in any release.
