I'm adding a colophon at the end of my document inside a \shapepar, however it appears at the top left of the page, and I can't manage to center it, both horizontally and vertically.
I've loaded the geometry options I'm loading for my document, but I removed basically all the preamble and a lot of packages that didn't seem to influence the positioning of the colophon.
Without the geometry package, it is somewhat centered but it still looks more to the left. Note that I included margins and a \newgeometry command to set the same margins for this page only, to simulate what happens in my actual document.
What's the most appropriate way to center it?
MWE
\documentclass[12pt, twoside]{article}
\usepackage[a4paper, margin=2.5cm,bindingoffset=1.5cm, showframe]{geometry}
\usepackage{shapepar}
\def\triangledownshape{%
{0}%
{0}b{0}\\%
{0}t{-10}{20}\\%
%{8.66}t{-5}{10}\\%
{17.32}e{0}%
}
\def\triangledownpar#1{\Shapepar\triangledownshape #1\unskip\ .\par}
\begin{document}
\newgeometry{margin=2cm}
\triangledownpar{Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut porttitor magna posuere tristique interdum. Maecenas ac nisi rutrum, tincidunt ante a, cursus est.
