Ammendment: Change to maxdrift value (App E)
Ammendment number: 08

Currently says:

After any horizontal movement, a final check is made as to
whether $\abs(Kh-{\it hh})>{\it max\_drift}$. If it is, then $\it
max\_drift$ is added or subtracted to $hh$ to bring it closer to
$Kh$. A similar check is made with $\it vv$ and $v$. $\it
max\_drift$ should be set to $2$ for output devices with device
units smaller than or equal to $1/200$ inches and $1$ for output
devices with device units with device units greater than $1/200$
inches.


Change to read:

   After any horizontal movement, a final check is made as to
   whether $\abs(Kh-{\it hh})>{\it max\_drift}$. If it is, then $\it
   max\_drift$ is added or subtracted to $hh$ to bring it closer to
   $Kh$. A similar check is made with $\it vv$ and $v$. $\it
|  max\_drift$ should be set to~2 for output devices with device
|  units smaller than or equal to $1/200$ inches, 1~for output
   devices with device units with device units greater than $1/200$
+  inches, and 0~for output devices with device units with device units
+  greater than $1/100$ inches.

Reason for change:

Previews usually have resolutions below 100 dpi. On a screen the
space between two words (usually two to three pixels!) should always
be recognizable, and should not be narrowed by a drift.
   With previews visualization of the interword space is more
important than equidistant widths between the characters of a word;
previews are often used for proofreading. After all we will not get
equidistant widths anyway.
