/**
 * Filters are simply functions that perform transformations on their first input argument.
 * Filters are run at render time, so they may not directly modify the compiled template structure in any way.
 * All of Swig's built-in filters are written in this same way. For more examples, reference the `filters.js` file in Swig's source.
 *
 * To disable auto-escaping on a custom filter, simply add a property to the filter method `safe = true;` and the output from this will not be escaped, no matter what the global settings are for Swig.
 *
 * @typedef {function} Filter
 *
 * @example
 * // This filter will return 'bazbop' if the idx on the input is not 'foobar'
 * swig.setFilter('foobar', function (input, idx) {
 *   return input[idx] === 'foobar' ? input[idx] : 'bazbop';
 * });
 * // myvar = ['foo', 'bar', 'baz', 'bop'];
 * // => {{ myvar|foobar(3) }}
 * // Since myvar[3] !== 'foobar', we render:
 * // => bazbop
 *
 * @example
 * // This filter will disable auto-escaping on its output:
 * function bazbop (input) { return input; }
 * bazbop.safe = true;
 * swig.setFilter('bazbop', bazbop);
 * // => {{ "<p>"|bazbop }}
 * // => <p>
 *
 * @param {*} input Input argument, automatically sent from Swig's built-in parser.
 * @param {...*} [args] All other arguments are defined by the Filter author.
