% By default, Beamer frames offer the |c| option to \textit{almost} vertically
|
|
% center the text, but the placement is a little too high. To fix this, we
|
|
% redefine the |c| option to equalize |\beamer@frametopskip| and
|
|
% |\beamer@framebottomskip|. This solution was suggested by Enrico Gregorio in
|
|
% an answer to \href{http://tex.stackexchange.com/questions/247826/}{this
