Why does tikz's positioning library add whitespace on the left side of my diagram?
With positioning:
\documentclass[border=1mm]{standalone}
\usepackage{tikz}
\begin{document}
\pagecolor{white}
\usetikzlibrary{positioning}
\begin{tikzpicture}[]
\draw (0,0) rectangle (7,4);
\end{tikzpicture}
\end{document}
Without positioning:
\documentclass[border=1mm]{standalone}
\usepackage{tikz}
\begin{document}
\pagecolor{white}
%\usetikzlibrary{positioning}
\begin{tikzpicture}[]
\draw (0,0) rectangle (7,4);
\end{tikzpicture}
\end{document}
There still seems to be a big of extra whitespace on the left, but not much.
