Dear NeWS Users;
	I am developing a software package using the NeWS windowing system.
The package employs zoom and scroll facilities.  The display is the mapping
of a network of system modules.  Each module is represented by a rectangle
with its id number and name written within the rectangle boundaries.

Problem:  When the scaling factor becomes very small (zoomed way out) as
it does when viewing a large system, the text looses proportion to the 
rectangles.  It appears too large and it also shifts so that much of it
is outside the rectangle.  The display behaves very nicely under conditions
of larger scaling factors.


Has anyone experienced this degredation before?  Any ideas?  Could it
be simply a loss of precision? (ie. roundoff or truncation error)

Thank you for your attention.  We now return you to the regularly
scheduled news.
