Correct as advertised above...
gdm has a full environment
gdm-binary has a full environment
gdm-simple-slave has a full environment
gdm-simple-greeter has a very minimal environment
gdm-session-worker has a full environment

Unfortunately, I do not have a full understanding of how GDM works, nor 
do I usually use it.  Only doing it now to assist with what little I 
can.  Why would the cancel button have a displayable icon, but not the 
logo and login button?  The fact that the cancel button icon shows up 
would seem to eliminate the need for XDG* in the greeter's environment.
