A #GParamSpec derived structure that contains the meta data for #GVariant properties.
When comparing values with gobject.global.paramValuesCmp, scalar values with the same
type will be compared with glib.variant.VariantG.compare. Other non-null variants will
be checked for equality with glib.variant.VariantG.equal, and their sort order is
otherwise undefined. null is ordered before non-null variants. Two null
values compare equal.
