/**
 * @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.
 *
 * To fix z-index problems in IE6, include the bgiframe plugin on your page
 * http://plugins.jquery.com/project/bgiframe - BeautyTips will automatically
 * recognize it and use it.
 *
 * BeautyTips also works with the hoverIntent plugin
 * http://cherne.net/brian/resources/jquery.hoverIntent.html
 * see hoverIntent example below for usage
 *
 * 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});
 *
 * For more/better documentation and lots of examples, visit the demo page included with the distribution
