I am trying to write a PHiGs type package for use on a Symbolics 3653
machine, but I am frustrated with the slow drawing using Symbolics' 
dynamic windows drawing primitives.  I have turned off output history
recording and have set up the listener to use fast scan conversion
but the output is still pitifully slow.  Has anyone out there found
a solution to this problem or is the LISP architecture just too slow?
