[XeTeX] "if" tests for italic / bold into new command?

[Andrew Moschou]

My metalogo package mentions these:

\ifdim\fontdimen\@ne\font\z@ is true if the current font is not slanted.
\if b\expandafter\@car\f at series\@nil is true if the current font is bold.

Here's an example:

\documentclass{article}

\makeatletter
\usepackage{fontspec}
\setmainfont{Georgia}

\newcommand\test{
  \ifdim\fontdimen\@ne\font=\z@
    Is upright
  \else
    Is italic or slanted
  \fi
  \if b\expandafter\@car\f at series\@nil
    Is bold
  \else
    Is not bold
  \fi}

\begin{document}
Something \test. \textit{Something \test.}

\bfseries Something \test. \textit{Something \test.}
\end{document}

It should be possible to to create new ifs based on these, say \ifbold and
\ifitalic, which I intend to put into the next update to metalogo.
