RE: NeWS on Sun

Is there a limit to the size NeWS allows on the scale and translate functions?
For example,

% this draws a 45 degree line
gsave -10 -20 translate 10 20 moveto 82 92 lineto stroke grestore

% but this doesn't:
gsave -100000 -200000 translate 100000 200000 moveto 100144 200144 lineto
stroke grestore

This doesn't cause an error, but it seems to be ignored.
I found that translate on the order of 10000 will work as advertized.
The problem can be fixed of course by prescaling the data before plotting,
but I don't see any reason ( at least from the NeWS manuals ) why this shouldn't
work.

Also, has anybody gone to the trouble of writing a key-repeat function 
in NeWS?  I suspect it is possible by waiting for the up-transition
a certain time after the down transition...
