/**
* @name Beauty Tips
* @type jQuery
* @cat Plugins/bt
* @return jQuery
* @author Jeff Robbins - Lullabot - http://www.lullabot.com
*
* @credit Inspired by Karl Swedberg's ClueTip
* (http://plugins.learningjquery.com/cluetip/), which in turn was inspired
* by Cody Lindley's jTip (http://www.codylindley.com)
*
* @fileoverview
* Beauty Tips is a jQuery tooltips plugin which uses the canvas drawing element
* in the HTML5 spec in order to dynamically draw tooltip "talk bubbles" around
* the descriptive help text associated with an item. This is in many ways
* similar to Google Maps which both provides similar talk-bubbles and uses the
* canvas element to draw them.
*
* The canvas element is supported in modern versions of FireFox, Safari, and
* Opera. However, Internet Explorer needs a separate library called ExplorerCanvas
* included on the page in order to support canvas drawing functions. ExplorerCanvas
* was created by Google for use with their web apps and you can find it here:
* http://excanvas.sourceforge.net/
*
* Beauty Tips was written to be simple to use and pretty. All of its options
* are documented at the bottom of this file and defaults can be overwritten
* globally for the entire page, or individually on each call.
*
* By default each tooltip will be positioned on the side of the target element
* which has the most free space. This is affected by the scroll position and
* size of the current window, so each Beauty Tip is redrawn each time it is
* displayed. It may appear above an element at the bottom of the page, but when
* the page is scrolled down (and the element is at the top of the page) it will
* then appear below it. Additionally, positions can be forced or a preferred
* order can be defined. See examples below.
*
* Usage
* The function can be called in a number of ways.
* $(selector).bt();
* $(selector).bt('Content text');
* $(selector).bt('Content text', {option1: value, option2: value});
* $(selector).bt({option1: value, option2: value});
*
* Some examples:
*
* @example
* $('[title]').bt();
* This is probably the simplest example. It will go through the page finding
* every element which has a title attribute and give it a Beauty Tips popup
* which gets fired on hover.
*
* @example
* $('h2').bt('I am an H2 element!', {trigger: 'click', positions: 'top'});
* When any H2 element on the page is clicked on, a tip will appear above it.
*
* @example
* $('a[href]').bt({
* titleSelector: "attr('href')",
* fill: 'red',
* cssStyles: {color: 'white', fontWeight: 'bold', width: 'auto'},
* width: 400,
* padding: 10,
* cornerRadius: 10,
* animate: true,
* spikeLength: 15,
* spikeGirth: 5,
* positions: ['left', 'right', 'bottom'],
* });
* This will find all <a> tags and display a red baloon with bold white text
* containing the href link. The box will be a variable width up to 400px with
* rounded corners and will fade in and animate position toward the target
* object when appearing. The script will try to position the box to the left,
* then to the right, and finally it will place it on the bottom if it does not
* fit elsewhere.
*
* @example
* $('#my-table td[title]').bt({
* preShow: function() {
* $(this).data('origBG', $(this).css('background-color'));
* $(this).css('background-color', 'yellow');
* },
* postHide: function() {
* $(this).css('background-color', $(this).data('origBG'));
* }
* });
* Find every table cell within #mytable with a title attribute. Hilight the cell
* yellow before displaying the BeautyTip. Restore it to its original background
* when hiding/removing the BeautyTip.
*
* @example
* $().bt.defaults.fill = 'rgba(102, 102, 255. .8)';
* $(selector).bt();
* All bubbles will be filled with a semi-transparent light-blue background
* unless otherwise specified.
