I am able to generate the following drawing:
In particular notice the nicely skewed text.
However, I know PSFRAG is kind of deprecated, and I would like to switch from the LATEX -> DVI -> PS -> PDF route to PDFLATEX or XELATEX. Therefore, I would like to find an alternative using a recent version of INKSCAPE.
I have tried:
\documentclass[12pt]{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}
\centering
\def\svgwidth{0.5\columnwidth}
\input{drawing.pdf_tex}
\caption{Notice the skewed text}
\end{figure}
\end{document}
but the result is not what I want:
TikZ is not an option. I am already very proficient with INKSCAPE.
