Add \ifpsfragfig conditional

[wspr]

While you can use \ifpdf to check what mode you're in, this isn't very self-documenting and might cause problems with code portability. For convenience it would be good to add a specific conditional for preamble code, etc., when psfragfig is processing an external figure.

Thanks @yo' on tex.sx

Yo comments additionally: "Actually… not 100% helpful; with \ifpdf or \pdfoutput, I could do the check for the documentclass as well, which is impossible with \ifpsfragfig since it won't be defined before \usepackage{pstool} in the main document"

Hello it's yo' here :) Thanks for considering this! As I said, there's a problem with \ifpsfragfig being defined everywhere, but as long as you can load pstool before \documentclass, all should be fine. Like this:

\RequirePackage{pstool}
\ifpsfragfig
  \documentclass[standalone]{myclass}
\else
  \documentclass{myclass}
\fi
