Unfortunately, the tool bar (and possible other operations) always
resize the frame.
-**** Support 'proced' (implement 'process-attributes')
-Unfortunately, a user-level process like Emacs does not have the
-privileges to get information about other processes under macOS.
-
-There are other ways to do this:
-
- 1) Spawn "ps" and parse the output ("ps" has superuser privileges).
-
- 2) Sign Emacs as part of the distribution process.
-
- 3) Ask the user to self-sign Emacs, if this feature is of interest.

-Anders Lindgren <andlind@gmail.com> has implemented
-'process-attributes' for macOS, which currently only work when
-running Emacs as root.

-See this article by Bozhidar Batsov for an overview of Proced:

**** Tooltip properties
Tooltip properties like the background color and font are hard-wired,
even though Emacs allows a user to customize such features.
