% PAGE Breaking
%\flushbottom % to stretch vboxes to cover full page
% (but won't always work when we have figures)
% Instead we can use the following:
\raggedbottom % allow textheight to vary somewhat between pages
\feetatbottom % to ensure footnotes are still at bottom with \raggedbottom

% Allowing the bottom to extend to avoid widows/orphans (WARNING, uneven lower margin)
%\setlength{\topskip}{1.6\topskip}
%\checkandfixthelayout
%\sloppybottom

% Since we use raggedbottom we can use fixed, it just sets textheight to the
\checkandfixthelayout[fixed] % use fixed to ensure margin sizes
% If we instead want to use flishbottom, we should probably set "lines" instead
