/**
 * If the user is calling <Spinner>…</Spinner> with children, it will take
 * precedence over theme styling. Yet, it will still inherit the
 * default animation and size of the spinner, and of course any additional
 * given props.
 *
 * If the user is providing an icon/svg via the theme.spinner.icon,
 * the Spinner will use it as a child and will include all its relevant
 * theme props (size/color/pad…) as well,
 * user will only need to type <Spinner />.
 * If the icon has its own animation, user can turn it off via the theme.
 *
 * If none of the above is provider, <Spinner /> will provide its default
 * border, size and friends, all configurable via theme or props.
