[XeTeX] geometry a3paper option error

[Daniel Greenhoe]

When I use the a3paper size option or papersize={297mm,420mm} with the
geometry package, graphics seem to get cut off to the right of 210mm
from the left edge (where the A4 right paper edge should be).

I am compiling with xelatex  Version 3.14159265-2.6-0.99991 (TeX Live
2014/W32TeX). I compiled a book cover using this same kind of
technique in 2013 using Version 3.1415926-2.5-0.9999.2 (TeX Live
2012/W32TeX) (format=xelatex 2013.4.4) with no problem.

A somewhat minimal example follows, and is also attached along with
pdf and log file to this email...

\documentclass{article}
\usepackage{pstricks}
\usepackage{geometry}
\geometry{
  xetex,truedimen,
  paper=a3paper,
  %papersize={297mm,420mm},% A3 paper dimensions
  centering,twoside=false,noheadfoot,nomarginpar,ignoreall,
  inner=10mm,outer=10mm,top=10mm,bottom=10mm,
  showframe
  }
\begin{document}%
\thispagestyle{empty}%
\mbox{}\vfill%
\psset{unit=1mm}%
\fbox{\begin{pspicture}(-130,-180)(130,180)%
  \psframe[linewidth=3pt,linecolor=red](-100,-50)(100,50)%
  \rput(0,0){\Huge$\cdot$}%
\end{pspicture}}%
\\\vfill%
\end{document}%

Many many thanks in advance,
Dan
