[tex-k] dvips/rounding problem

[Tomas G. Rokicki]

But zero maxdrift for rules is wrong too, since some characters are
composed of glyphs and rules (long arrows for instance) and you can
end up then with a gap between the rule and the glyph . . .

A better fix would be to be smarter about rules in general,
recognize when they line up (dvips preprocesses anyway) and
line up just those that are supposed to line up . . . I don't
know if this is possible in general, but the common case of a
rule on the right side of a table shouldn't be too hard to
catch . . .
