+/**
+ * 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.
