*
* @projectDescription Easy element scrolling using jQuery.
* http://flesler.blogspot.com/2007/10/jqueryscrollto.html
* Works with jQuery +1.2.6. Tested on FF 2/3, IE 6/7/8, Opera 9.5/6, Safari 3, Chrome 1 on WinXP.
*
* @author Ariel Flesler
* @version 1.4.2
*
* @id jQuery.scrollTo
* @id jQuery.fn.scrollTo
* @param {String, Number, DOMElement, jQuery, Object} target Where to scroll the matched elements.
* The different options for target are:
* - A number position (will be applied to all axes).
* - A string position ('44', '100px', '+=90', etc ) will be applied to all axes
* - A jQuery/DOM element ( logically, child of the element to scroll )
* - A string selector, that will be relative to the element to scroll ( 'li:eq(2)', etc )
* - A hash { top:x, left:y }, x and y can be any kind of number/string like above.
* - A percentage of the container's dimension/s, for example: 50% to go to the middle.
* - The string 'max' for go-to-end.
* @param {Number} duration The OVERALL length of the animation, this argument can be the settings object instead.
* @param {Object,Function} settings Optional set of settings or the onAfter callback.
* @option {String} axis Which axis must be scrolled, use 'x', 'y', 'xy' or 'yx'.
* @option {Number} duration The OVERALL length of the animation.
* @option {String} easing The easing method for the animation.
* @option {Boolean} margin If true, the margin of the target element will be deducted from the final position.
* @option {Object, Number} offset Add/deduct from the end position. One number for both axes or { top:x, left:y }.
* @option {Object, Number} over Add/deduct the height/width multiplied by 'over', can be { top:x, left:y } when using both axes.
* @option {Boolean} queue If true, and both axis are given, the 2nd axis will only be animated after the first one ends.
* @option {Function} onAfter Function to be called after the scrolling ends.
* @option {Function} onAfterFirst If queuing is activated, this function will be called after the first scrolling ends.
* @return {jQuery} Returns the same jQuery object, for chaining.
*
* @desc Scroll to a fixed position
* @example $('div').scrollTo( 340 );
*
* @desc Scroll relatively to the actual position
* @example $('div').scrollTo( '+=340px', { axis:'y' } );
*
* @dec Scroll using a selector (relative to the scrolled element)
* @example $('div').scrollTo( 'p.paragraph:eq(2)', 500, { easing:'swing', queue:true, axis:'xy' } );
*
* @ Scroll to a DOM element (same for jQuery object)
* @example var second_child = document.getElementById('container').firstChild.nextSibling;
* $('#container').scrollTo( second_child, { duration:500, axis:'x', onAfter:function(){
* alert('scrolled!!');
* }});
*
* @desc Scroll on both axes, to different values
* @example $('div').scrollTo( { top: 300, left:'+=200' }, { axis:'xy', offset:-20 } );
