%%  Version History
%%
%%  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
