%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Version History
%%
%% 2016/07/11 [DPC] [v4.10] \mag test added to all the files
%% Remove spurious dependency on external packages.
%% Avoid \@ehd help text (not defined by miniltx)
%%
%% 2016/07/02 [DPC] [v4.09] support new (no)setpagesize options of
%% color and graphics packages.
%% revert pagecolor code to match dvips
%%
%% 2016/04/06 [AK] [v4.08] Support new suffix .mps (or .MPS) for eps files
%% created by MetaPost. In TeX Live 2016, the option --mvorigin
%% for [x]dvipdfmx is necessary to include MetaPost-created eps
%% files by the usual \Ginclude@eps. This may a bit be inconvenient.
%% Thus we introduce a new command \Ginclude@mps for the suffix
%% .mps (or .MPS). In \Ginclude@mps, llx, lly, urx, and ury are
%% natural compared with those in \Ginclude@eps. Thus the origin
%% should not be translated, that is the option --mvorigin should
%% not be given.
%%
%% 2015/09/11 [AK, NA, TY] [v4.06] Support pagebox=artbox, etc. in xelatex,
%% like in pdflatex. It requires new xetex and xdvipdfmx, which
%% will be available in TeX Live 2016. Interested users may build
%% new binaries by using new sources in the TeX Live repository.
%%
%% 2015/03/26 [SH] [v4.04] JPEG 2000 (.jp2, .jpf) support, written for
%% dvipdfmx.
%%
%% 2014/04/28 [KB] [v4.03] \newif outside \def. Skipped 4.02.
%%
%% 2014/04/28 [HO] [v4.01] .CAPS extensions.
%% [KB] ordering: find .jpeg just after .jpg,
%% more like dvipdfmx.def. Also remove .sga/.sgi,
%% which were mismatched and never noticed.
%% Change version number to match dvipdfmx.def.
%%
%% 2014/04/07 [AK] [v0.99] remove spurious spaces.
%%
%% 2014/03/24 [AK] [v0.98] non-origin viewport, avoid double bp conversion.
%%
%% 2014/03/21 [KB] doc tweaks for project home at puszcza.gnu.org.ua.
%%
%% 2013/05/27 [KB] Version v0.97 non-commutative operations.
%% (code provided by Bruno Voisin)
%%
%% 2013/04/29 [KB] Version v0.96 handle non-origin ll corner.
%% (code provided by Bruno Voisin)
%%
%% 2013/02/04 [RRM] Version v0.95 added clipping support.
%% (code provided by Joseph Wright and Martin Scharrer)
%%
%% 2009/11/21 [KB] Version v0.94 merge the two 0.93's.
%%
%% 2009/10/28 [RRM] Version v0.93 fix big-point incompatibility;
%%
%% 2007/10/25 [JK] Version v0.93 added EPS support from dvipdfmx.def
%% (for use with xdvipdfmx, default driver in xetex 0.997)
%%
%% 2006/08/10 [JK] Version v0.92 correct type-check in \G@measure@QTm;
%% remove \G@PDF@ext, apply \lowercase instead;
%% make \XeTeXquote have catcode 12 rather than 11;
%% explicit space after "filename.ext" (reqd by xetex 0.995)
%%
%% 2006/07/19 [JK] Version v0.91 use \special{color ...} rather than
%% \special{x:textcolor ...} etc, for compatibility with
%% both xdv2pdf and xdvipdfmx drivers;
%% added .bmp to list of recognized graphics extensions
%%
%% 2006/01/09 [JK] Version v0.9 removed support for XeTeX versions
%% prior to 0.6 (when the \XeTeXpicfile parameters were
%% modified), to avoid problem when \XeTeXrevision inc. letters
%%
%% 2005/10/12 Version v0.8 removed spurious space in \convertHEX@
%% -- found by Morten Hogholm
%%
%% 2004/05/09 Version v0.7 changed support for \pagecolor, adapted
%% from pdftex.def, to put a \special in the \shipout ;
%% this driver should now work with miniltx.tex ;
%% changed some control-sequence names;
%% implemented HSB to RGB color conversion
%% identified the redundant (v0.5) coding more clearly.
%%
%% 2004/05/08 Version v0.6 properly implements scaling and rotations
%% following the coding used with pdftex.def ;
%% implemented `viewport' and prepared for `clip';
%% don't rely on " to have correct catcode;
%% altered the suffix order for graphics, to be:
%% .pdf .png .jpg .pict .tif ....
%%
%% 2004/04/29 Version v0.5 adapts to the changed names for the
%% graphics inclusion primitives, and version strings.
%%
%% 2004/04/23 Version v0.41 works with graphics.sty as well as
%% graphicx.sty ; \G@pdf@ext is '.pdf';
%% similarly define and use \G@PDF@ext for '.PDF';
%% removed some log-messages.
%%
%% 2004/04/22 Version v0.4 designed to work with XeTeX v0.4

% In the above \Ginclude@eps, llx, lly, urx, and ury are translated to match
% the -dEPSCrop option for Ghostscript to convert eps to pdf.
% In the case of eps files created by MetaPost, the files are included
% directly without the help of Ghostscript. That is, we have to translate
% the origin accordingly if we use \Ginclude@eps for eps files created by
% MetaPost. In TeX Live 2015, the translation of the origin was the default.
% After TeX Live 2016, however, the translation of the origin is enabled only
% if the --mvorigin option is given for dvipdfmx or xdvipdfmx.
% This may be a bit inconvenient, especially in the case of XeTeX where
% xdvipdfmx is usually called as a pipe. Therefore we introduce a new suffix
% .mps(or .MPS) to support inclusion of eps files created by MetaPost without
% the option --mvorigin.
