  Hi all.

  I am using a personal laser writer IInt for some homebrew postscript
pictures involving lots of filled rectangles.  Someone has told me that
there is a modification to the setgrray routines that will improve them.
(By eyeball, it looked like they were basing the grey fills at 75 or 
a hundred dpi at most -- the pixels they filled in to get thier fills
were somewhat larger than 1/300th of an inch)

  Does anyone know of such a set of routines?  It looks like we are
getting 32-64 distinct grey levels; I thought a 300 dpi printer could do
better.

  Please reply directly if possible; I tend to get way behind in this group.
