 *  Modified by Mac Chan                                        *
 *  - pretty print and fix all errors reported by JSLint        *
 *  - include a 14k packed version                              *
 *  - change method name from corner() to curvy() to avoid      *
 *    conflict with other plugin                                *
 *  - options can be passed as object literal                   *
