[XeTeX] Colour specials for XeTeX

[Philip Taylor]

Thank you all for your comments and explanations.  One question to Akira-san, though :

> If you use -no-pdf option and apply xdvipdfmx to a created

> xdvipdfmx:warning: xetex-style \special{x:rulecolorpush} is
> not supported by this driver;

Is there any way (perhaps through a command-line option to XeTeX) that one could obtain those most usedful diagnostics using XeTeX in "standard" mode, i.e. without using the "-no-pdf" option and without running xdvipdfmx explicitly ?
