This is not a bug, but an implementation limit.  NeWS always tries to use
a bitmap font.  There is no 150 point Times-Roman in the font directory.
If you do the following.

/Times-Roman findfont 
150 scalefont setfont	
100 100 moveto		
(AAAA) show	

You will notice that the spacing between characters is for a 150 point 
version, although something around 72 points is displayed.  When you did
the 1 rotate you faked out the font machinery inside of NeWS.  It looked at
the Current Transformation Matrix and decided that you were not doing a 
simple scale operation. It therefore computed the glyph for (A) on the fly.
Notice how poor the second glyph looks. 

If you want big glyphs do something like .001 rotate, or add some big bitmap
fonts into your font directory.

If you look closely at the "Text (scaled)" demo you will notice that the 
same bitmap font gets used about 3 times in a row.
