DEFINE_PROP_ON_OFF_AUTO_BIT64() corresponds to DEFINE_PROP_ON_OFF_AUTO()
as DEFINE_PROP_BIT64() corresponds to DEFINE_PROP_BOOL(). The difference
is that DEFINE_PROP_ON_OFF_AUTO_BIT64() exposes OnOffAuto instead of
bool.

Does it mean that the name of this tristate type is "bool"? Or I miss something?

No, this should be OnOffAuto. Thanks for pointing out this; I'll fix 
this in the next version.
