- * @id jQuery.scrollTo\r
- * @id jQuery.fn.scrollTo\r
- * @param {String, Number, DOMElement, jQuery, Object} target Where to scroll the matched elements.\r
- * The different options for target are:\r
- * - A number position (will be applied to all axes).\r
- * - A string position ('44', '100px', '+=90', etc ) will be applied to all axes\r
- * - A jQuery/DOM element ( logically, child of the element to scroll )\r
- * - A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )\r
- * - A hash { top:x, left:y }, x and y can be any kind of number/string like above.\r
- * @param {Number} duration The OVERALL length of the animation, this argument can be the settings object instead.\r
- * @param {Object,Function} settings Optional set of settings or the onAfter callback.\r
- * @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.\r
- * @option {Number} duration The OVERALL length of the animation.\r
- * @option {String} easing The easing method for the animation.\r
- * @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.\r
- * @option {Object, Number} offset Add/deduct from the end position. One number for both axes or { top:x, left:y }.\r
- * @option {Object, Number} over Add/deduct the height/width multiplied by 'over', can be { top:x, left:y } when using both axes.\r
- * @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.\r
- * @option {Function} onAfter Function to be called after the scrolling ends. \r
- * @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.\r
- * @return {jQuery} Returns the same jQuery object, for chaining.\r
- *\r
- * @desc Scroll to a fixed position\r
- * @example $('div').scrollTo( 340 );\r
- *\r
- * @desc Scroll relatively to the actual position\r
- * @example $('div').scrollTo( '+=340px', { axis:'y' } );\r
- *\r
- * @dec Scroll using a selector (relative to the scrolled element)\r
- * @example $('div').scrollTo( 'p.paragraph:eq(2)', 500, { easing:'swing', queue:true, axis:'xy' } );\r
- *\r
- * @ Scroll to a DOM element (same for jQuery object)\r
- * @example var second_child = document.getElementById('container').firstChild.nextSibling;\r
- * $('#container').scrollTo( second_child, { duration:500, axis:'x', onAfter:function(){\r
- * alert('scrolled!!'); \r
- * }});\r
- *\r
- * @desc Scroll on both axes, to different values\r
- * @example $('div').scrollTo( { top: 300, left:'+=200' }, { axis:'xy', offset:-20 } );\r
