Oh, certainly.  My goal was to make all the original PDP-10 and PDP-11
code run, and have it print something close to the original XGP.
Bypassing and essentially reimplementing the rendering done in the
PDP-11 would make it possible to output text instead of graphics.

Look in files called xgp, meatball, and print.  Perhaps what you're
after is in the function downsample.

Yes, to the first part.  Regarding what the PDP-11 does, probably.

I shudder at the thought.

I think this is a strained argument to make.  My guess is no archivist
will care if a document is 1K or 1M in size.  Be that as it may, you
don't have to convince anyone, just go ahead and do it if you want to.
I'm sorry to say much of your message looks like LLM output.
