### Inverted pyramid typesetting

University thesis committees are fairly well-known in the typesetting world for having the most absurd requirements. One example requires heading text to be typeset centered and no more than 4.5 in wide in which the lines become progressively shorter.

This is stupid. Still, I've got a solution, based on egreg's:
``````\newcommand\stupid[1]{%
\vbox{%
\hsize=4.5in
\parindent=0pt
\leftskip=0pt plus.5fil
\rightskip=0pt plus-0.5fil
\parfillskip=0pt plus1fil
\emergencystretch=1in
\parshape6
0.00in 4.50in
0.25in 4.00in
0.50in 3.50in
0.75in 3.00in
1.00in 2.50in
1.25in 2.00in
\huge
\bfseries
\strut
#1%
}%
}``````
The `\parshape` specifies what to do for the first 6 lines by giving pairs of numbers. The first in the pair is the indentation and the second is the line length. The settings of `\leftskip`, `\rightskip`, and `\parfillskip` come from TeX by Topic and are used to center the last line.
