/**
 * @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.
