% Print a rule.  Normally this is done with a filled area defined by rlineto.
% Unfortunately, doing it this way introduces a 1 pixel error on some
% PostScript printer implementations.  In order to get exactly correct
% pixel size and positioning, an alternate approach is implemented under
% control of boolean "PreciseRulePositioning".  With this approach,
% we create a temporary font in which the rule is the only character.
% Since the alternate mechanism causes documents with lots of rules to
% print much more slowly, and since the 1 pixel maximum difference is
% rarely noticed, it is not used by default.  Enable it by setting
% "PreciseRulePositioning" true.
