Actually, resource_changed is not supposed to create a copy immediately.
Maybe instead of "trigger recreation of derived internal resources" it
should be described as "mark resource as changed so derived internal
resources will be recreated on next use".

Contrary to flush_resource, which has an immediate, externally visible
effect for which a context may be needed, resource_changed can just
update some internal state. The changed resource should be marked as
changed for all contexts, which is why I saw no reason to call
resource_changed with any one specific context.


Sounds good to me.
