Ammendment: definition of round() in section 2.6.2
Ammendment number: 09
Submitted by: Joachim Schrod <xitijsch@ddathd21.bitnet>
Date: 14 Nov 90


Reason for change:

This ammendment changes the name of the function round() in Section
2.6.2 to pixel_round() and defines pixel_round().
   Please note that the change of the name was done in the macro
\round.

The ammendment is given as a context diff, assuming draft 0.04a at
it's base. This new ammendment results in the draft 0.04b.
