/* Why reinterpret_cast<Caps*>(gobject) is needed:
 *
 * A Caps instance is in fact always a GstCaps instance.
 * Unfortunately, GstCaps cannot be a member of Caps,
 * because it is an opaque struct.  Also, the C interface does not provide
 * any hooks to install a destroy notification handler, thus we cannot
 * wrap it dynamically either.
 *
 * The cast works because Caps does not have any member data, and
 * it is impossible to derive from it.  This is ensured by not implementing
 * the (protected) default constructor.  The ctor is protected rather than
 * private just to avoid a compile warning.
