I said "traditionally": there your primary "login" is a shell.
For X and graphical environments, it's another story.

Right -- I mentioned that for completeness, since this is a recurring
pattern: a system-wide config which can be overridden per user.

No need: those are shell snippeds sourced by the X session shell,
which will be the mother of all your X processes -- and PATH is
part of their inherited environment. Setting PATH there will be
inherited by those.

But see Dan's other take -- pam will set things (among others
the PATH for any authentication which goes via PAM (i.e. the
display manager, where you log into X, a shell in a console,
or even an ssh from another box).
