I haven't looked at this graphics terminal code in a while, so of course it's bit-rotted and I have an impossible to debug
Exception in cadr: incorrect list structure #f

And the debugger stops at least one or two levels up from the function that really did this.

So now my code's full of (errprintln) like a primitive again.

Finally found an untested error path, added a test & message, changed a 128 to 256, and it's fine.

SIGH. Literally 2 cups of coffee and an hour of flailing.
