%
% 2015-03-21 David A. Shamma Updating for new format and Github
% repo for CHI 2016.

%
% 1999-09-11 Gerry Murry Allowance Made to switch default fonts
% between those systems using METAFONT and those using 'Type 1' or
% 'Truetype' fonts. See LINE NUMBER 266 for details. Also provided
% for enumerated/annotated Corollaries 'surrounded' by enumerated
% Theorems (line 838).
%
% Modified from ACM_PROC_ARTICLE-SP DOCUMENT STYLE by G.K.M. Tobin
% August-October 1999. Adapted from ARTICLE document style by Ken
% Traub, Olin Shivers also using elements of esub2acm.cls. Modified
% from ARTICLE DOCUMENT STYLE -- Released 16 March 1988 for LaTeX
% version 2.09 by Leslie Lamport, 16 March 1988.
%
% MISC:
%
% Fixed the format to match the Word template and added a \teaser
% command to add a teaser image.
%
% Made the Permission Statement / Conference Info / Copyright Info
% 'user definable' in the source .tex file OR automatic if not
% specified. This 'sp' version does NOT produce the permission block.
%
% Major change in January 2000 was to include a "blank line" in
% between new paragraphs. This involved major changes to the, then,
% acmproc-sp.cls 1.0SP file, precipitating a 'new' name:

%%% ACM_PROC_ARTICLE-SP is a document style for producing two-column camera-ready pages for
%%% ACM conferences, according to ACM specifications. The main features of
%%% this style are:
%%%
%%% 1) Two columns.
%%% 2) Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of
%%% 2pc, hence columns are 20pc wide and 55.5pc tall. (6pc =3D 1in, approx)
%%% 3) First page has title information, and an extra 6pc of space at the
%%% bottom of the first column for the ACM copyright notice.
%%% 4) Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
%%%
%%%
%%% There are a few restrictions you must observe:
%%%
%%% 1) You cannot change the font size; ACM wants you to use 9pt.
%%% 3) You must start your paper with the \maketitle command. Prior to the
%%% \maketitle you must have \title and \author commands. If you have a
%%% \date command it will be ignored; no date appears on the paper, since
%%% the proceedings will have a date on the front cover.
%%% 4) Marginal paragraphs, tables of contents, lists of figures and tables,
%%% and page headings are all forbidden.
%%% 5) The `figure' environment will produce a figure one column wide; if you
%%% want one that is two columns wide, use `figure*'.
%%%
%
%%% Copyright Space:
%%% This style automatically leaves 1" blank space at the bottom of page 1/
%%% column 1. This space can optionally be filled with some text using the
%%% \toappear{...} command. If used, this command must be BEFORE the \maketitle
%%% command. If this command is defined AND [preprint] is on, then the
%%% space is filled with the {...} text (at the bottom); otherwise, it is
%%% blank. If you use \toappearbox{...} instead of \toappear{...} then a
%%% box will be drawn around the text (if [preprint] is on).
%%%
%%% A typical usage looks like this:
%%% \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian
%%% Embalming Technique, June 1991, Alfaretta, Georgia.}
%%% This will be included in the preprint, and left out of the conference
%%% version.
%%%
%%% WARNING:
%%% Some dvi-ps converters heuristically allow chars to drift from their
%%% true positions a few pixels. This may be noticeable with the 9pt sans-serif
%%% bold font used for section headers.
%%% You may turn this hackery off via the -e option:
%%% dvips -e 0 foo.dvi >foo.ps
%%%

% Rationale for changes made in next four definitions:
% "Before skip" is made elastic to provide some give in setting columns (vs.
% parskip, which is non-elastic to keep section headers "anchored" to their
% subsequent text.
%
% "After skip" is minimized -- BUT setting it to 0pt resulted in run-in heads, despite
% the documentation asserted only after-skip < 0pt would have result.
%
% Baselineskip added to style to ensure multi-line section titles, and section heads
% followed by another section head rather than text, are decently spaced vertically.

%% DanCo, 10/19/11: Added this to reduce overfull lines per Sheridan
%% request; it leads to occasionally unpleasant extra whitespace,
%% though actually no worse and perhaps better than the
%% default Word template.
%%
%% This can be manually controlled instead by authors in text
%% by putting \sloppy before and \fussy immediately
%% after troublesome paras. Idea found at
