% Driver commands for dvipdfmx
%
% Modified by Jin-Hwan Cho <chofchof@ktug.or.kr> on April 18, 2009.
% This driver requires the version DVIPDFMX-20080605 that is contained
% in texlive 2008 or later.

% `pdf:code' is an abbreviation of `pdf:literal direct', the idea of which
% came from pdfTeX's primitive \pdfliteral direct.

% If color is changed by \pgfsys@invoke explicitly, the color
% optimization routine in dvipdfmx does not work correctly
% because the routine checks color specials only. For example,
%
% \special{color push 0}\pgfsys@invoke{1 g 1 G}\special{color push 0}
%
% the last color special will be ignored the optimization routine
% thinks that the color has changed to the same color.
% To avoid this problem, we need to change the color temporarily to another.
%
% We assume that black is the default color when no color is specified.
