Transfer modes for ref-counted return values that may have a floating reference

[Phil Clayton <phil clayton veonix com>]

Based on the description of transfer modes at
https://wiki.gnome.org/Projects/GObjectIntrospection/Annotations/
I was assuming that bindings are expected to do the following for a 
ref-counted return value that may have a floating reference:

if transfer-ownership=full: take over ref
if transfer-ownership=none: ref-sink and take over ref

(quoting from https://bugzilla.gnome.org/show_bug.cgi?id=657202#c1)
Is this still the case?  Or has it changed to:

if transfer-ownership=full, floating=true: ref-sink and take over ref
if transfer-ownership=full, floating=false: take over ref
if transfer-ownership=none: ref-sink and take over ref

Thanks,
Phil
