The following anomolous phenomena were observed in the process of making up ps3

1. My EDWIN (in /usr/local/bin/edwin) 
    seems to have some problem with the tty settings
    needs -constant 1600 to gobble up 6001.

     I type: edwin -constant 1600 -band 6001.com

2. M-X load-problem-set 3 
    bombs looking for set-buffer-writable!

     Chris says there is a typo in the system.


I fixed 3, 4 in the file picture.scm

3. ps3go.scm had a setting for the width/height of 257... 
    I don't see why 256 isn't right.

4. graphics-draw-line in a window that is not painted black loses, 
    even though it looks black.


Ugh:

5. I don't know how to print a graphical image.



6. I need to be able to latex stuff from MAC... 
    I must noop a picture macro.

7. I need to find spring-92 version to get pictures from.
