This is the "application delegate", the object messaged if the true
Application object doesn't understand a message. We use this as a
sort of substitute for main().
We're actually vended as a distributed object--other processes or
threads within this process can hook up to us and send us messages.
This is done to serialize output to the windowserver and appkit--
otherwise we run into problems with critical sections.
We initialize some things in appDidInit:. When the user hits one
of the menu items, we get the message and act upon it.
This is not in any way, shape, or form optimized for speed. There
are a bunch of things that could be done to speed things up. The
biggest offendor is probably the CircleView class, which is banging
on the window server in various ways.
This file is set up for a width of 130 columns, with tab stops
every two spaces.
