Ammendment: Change margin of error tolerance (S4.3.2)
Ammendment number: 01
Submitted by: Don Hosek <dhosek@ymir.claremont.edu>

Currently says:
If a DVI file requests a magnification within 2% of a supported
magnification, the driver should use that font without warning.

Change to read:
TeX and METAFONT compute font magnifications with different
precisions.  Further, calculations done by TeX and/or a DVI
driver are subject to roundoff errors.  As a method of
accomodating these calculations, if the magnification requested
for a font is within 0.2% of a supported magnification, the
driver should use the supported magnification without warning.

Reason for change:
In discussion on DRIV-L, it was shown that rounding errors would
not cause a variation greater than 0.2% (and that only in extreme
cases at high resolutions). Tom Reid, in his mail of 3-July-1990
gives the numerical proof of this as well as a simple algorithim
for handling locating the font when calculations are off slightly
as indicated. The purpose of the rounding error calculation is
*not* to do things like take care of the case where a user
requested cmr10 at 11pt instead of cmr10 at 10.95pt.
