Hello Eli,

I had a long conversation with you in May 2016[1] about understanding the
best place/hook for graphics related setup (like fonts) in emacs config,
when running emacsclient.

As I later learned in that conversation, neither after-init-hook nor
emacs-startup-hook were the right place for that.
after-make-frame-functions was also not good unless the frame is selected
(which is not the case in emacsclient/daemon). So focus-in-hook turned out
to be the best place were I can check if a certain font was available etc.

I have read through (elisp) Startup Summary, but it does not reference
after-make-frame-functions and its caveat with emacsclient. It also does
not reference focus-in-hook.

I believe having that information in that section will be very valuable to
other users using emacsclient in GUI frame.

Copying Rob on this as he had a similar question he asked me off the list.
