+    <h1>BeautyTips Demo</h1>
+    <p><img src="demofiles/logo.png" alt="BeautyTips" width="240" height="200" style="float:right;margin-left:10px;margin-bottom:5px" />BeautyTips is a jQuery tooltips plugin which uses the canvas drawing
+      element
+      in the HTML5 spec in order to dynamically draw tooltips (sometimes called "talk bubbles" or "help balloons")
+      associated with a html element on the page. These tips are highly configurable and can be triggered in many different ways.</p>
+    <p> 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. <a href="http://excanvas.sourceforge.net/">ExplorerCanvas</a>
+      was created by Google for use with their web apps and you can find it <a href="http://excanvas.sourceforge.net/">here</a>.</p>
+    <p>BeautyTips was written to be simple to use and pretty. All of its options
+      are documented at the bottom of the .js file and defaults can be overwritten
+      globally for the entire page, or individually for each target element (more about this in the wrapup section).</p>
+    <p>BeautyTips has been tested with jQuery 1.2.6 and 1.3 on Firefox 3.x, Safari 3.x (also works on iPhone!), IE 6.x+, and Opera 8+, but I'm sure other canvas-capable browsers will work as well.</p>
+    <p> 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 appear below it. Additionally, positions can be forced or a preferred
+      order can be defined. See examples below.</p>
+    <h2>Project Page and Download</h2>
+    <p>BeautyTips has <a href="http://plugins.jquery.com/project/bt">a page</a> in the plugins directory on jQuery.com. This is where you can download the latest version. It is also the best place to post bugs and feature requests.</p>
+    <p><a href="http://plugins.jquery.com/project/bt">http://plugins.jquery.com/project/bt</a></p>
+    <h2>Other helpful plugins</h2>
+    <p>To fix z-index problems with form elements in IE6, include the <a href="http://plugins.jquery.com/project/bgiframe">bgiframe plugin</a> on your page. BeautyTips will automatically
+      recognize it and use it.</p>
+    <p>BeautyTips also works with the <a href="http://cherne.net/brian/resources/jquery.hoverIntent.html">hoverIntent plugin</a>
+      see hoverIntent example below for usage.</p>
+    <h2>Usage</h2>
+      <p>The function can be called in a number of ways.<br>
+      <code>$(selector).bt();</code><br>
+      <code>$(selector).bt('Content text');</code><br>
+      <code>$(selector).bt('Content text', {option1: value, option2: value});</code><br>
+      <code>$(selector).bt({option1: value, option2: value});</code></p>
+    <h2>Examples</h2>
+    <p><small>Note: html and javascript textareas are live. Feel free to experiment with the code and see how BeautyTips are affected.</small></p>

+    <div class="desc">
+    <p>This is  the simplest example. No arguments are sent and the default settings
+    are used to create a tip which appears on the side with the most space.</p>

+    <div class="desc">
+    <p>This example uses the contentSelector attribute to determine where the content comes from. In this case the selector is <code>$(this).attr('href')</code> and the content is the href attribute of the hovered link. Other options define a red balloon with bold white text. The box will be a variable width up to 400px ("width: 'auto' in cssStyles makes text box shrink-to-fit) with rounded corners. 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.</p>

+/**
+ * @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
+ *

+					<dd class="answer">
+						<p>The usage is simple. Just call <code>bgiframe</code> on a jQuery collection of elements.</p>
+						<p><code>$('.fix-z-index').bgiframe();</code></p>
+						<p>The plugin tries its best to handle most situations but sometimes some configuration is necessary. For example if your borders are defined in a unit other than pixels, you will need to manually set the <code>top</code> and <code>left</code> properties to the negative width of the border. Here are the options/settings available to configure the output.</p>
+						<dl id="options">

+							<dd>
+								<p>The iframe must be offset to the top by the width of the top border. This should be a negative number representing the border-top-width. If a number is is used here, pixels will be assumed. Otherwise, be sure to specify a unit. An expression could also be used. By default the value is "auto" which will use an expression to get the border-top-width if it is in pixels.</p>

+						<p>The bgiframe plugin works by prepending an iframe to the element. The iframe is given a class of bgiframe and positioned below all the other children of the element.

The element needs to have position (relative or absolute) and should have a background (color or image).</p>

+/**
+ * The bgiframe is chainable and applies the iframe hack to get 
+ * around zIndex issues in IE6. It will only apply itself in IE6 
+ * and adds a class to the iframe called 'bgiframe'. The iframe
+ * is appeneded as the first child of the matched element(s) 
+ * with a tabIndex and zIndex of -1.
+ * 
+ * By default the plugin will take borders, sized with pixel units,
+ * into account. If a different unit is used for the border's width,
+ * then you will need to use the top and left settings as explained below.
+ *
+ * NOTICE: This plugin has been reported to cause perfromance problems
+ * when used on elements that change properties (like width, height and
+ * opacity) a lot in IE6. Most of these problems have been caused by 
+ * the expressions used to calculate the elements width, height and 
+ * borders. Some have reported it is due to the opacity filter. All 
+ * these settings can be changed if needed as explained below.
+ *
+ * @example $('div').bgiframe();
+ * @before <div><p>Paragraph</p></div>
+ * @result <div><iframe class="bgiframe".../><p>Paragraph</p></div>
+ *
+ * @param Map settings Optional settings to configure the iframe.
+ * @option String|Number top The iframe must be offset to the top
+ * 		by the width of the top border. This should be a negative 
+ *      number representing the border-top-width. If a number is 
+ * 		is used here, pixels will be assumed. Otherwise, be sure
+ *		to specify a unit. An expression could also be used. 
+ * 		By default the value is "auto" which will use an expression 
+ * 		to get the border-top-width if it is in pixels.
+ * @option String|Number left The iframe must be offset to the left
+ * 		by the width of the left border. This should be a negative 
+ *      number representing the border-left-width. If a number is 
+ * 		is used here, pixels will be assumed. Otherwise, be sure
+ *		to specify a unit. An expression could also be used. 
+ * 		By default the value is "auto" which will use an expression 
+ * 		to get the border-left-width if it is in pixels.
+ * @option String|Number width This is the width of the iframe. If
+ *		a number is used here, pixels will be assume. Otherwise, be sure
+ * 		to specify a unit. An experssion could also be used.
+ *		By default the value is "auto" which will use an experssion
+ * 		to get the offsetWidth.
+ * @option String|Number height This is the height of the iframe. If

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+ExplorerCanvas
+Copyright 2006 Google Inc.
+
+-------------------------------------------------------------------------------
+DESCRIPTION
+
+Firefox, Safari and Opera 9 support the canvas tag to allow 2D command-based 
+drawing operations. ExplorerCanvas brings the same functionality to Internet 
+Explorer; web developers only need to include a single script tag in their 
+existing canvas webpages to enable this support.
+
+
+-------------------------------------------------------------------------------
+INSTALLATION
+
+Include the ExplorerCanvas tag in the same directory as your HTML files, and 
+add the following code to your page, preferably in the <head> tag.
+
+
+
+If you run into trouble, please look at the included example code to see how
+to best implement this

-/* jQuery Drag and Drop Library for Rich Editors
- *
- * A helper library which provides the ability to drag and drop images to Rich 
- * Text Editors (RTEs) that use the embedded iframe + DesignMode method. DnD
- * also provides a simple "clicky" interface for inserting the same markup 
- * directly into a textarea.  
- *
- * Basic usage:
- *
- * $('img.my-class').dnd({targets: $('#my-iframe')});
- *
- * Options:
- *
- * targets (Required):
- *   A jQuery object corresponding to the proper iframe(s) and/or textarea(s)
- *   that are allowed drop targets for the current set of elements.
- *
- * idSelector:
- *  A callback that parses out the unique ID of an image that is dropped in an 
- *  iframe.  While some browsers (such as Firefox and Internet Explorer) allow
- *  markup to be copied when dragging and dropping, Safari (and assumably
- *  other webkit based browsers) don't.  The upshot is that the safest bet is
- *  to parse the element's src URL.  Because querystrings seem to drop 
- *  consistently across 
- *
- * processIframeDrop:
- *   A callback that defines the mechanism for inserting and rendering the 
- *   dropped item in an iframe.  The typical usage pattern I expect to see is
- *   that implementers will listen for their RTE to load and then invoke DnD
- *   with a processIframeDrop appropriate to their editor.
- *
- * processTextAreaDrop:
- *   A callback that defines the mechanism for inserting and rendering the
- *   clicked item in a textarea.  The default function just tries to insert
- *   some markup at the caret location in the current textarea.
- *
- * interval:
- *   How often to check the iframe for a drop, in milliseconds.
- *
- * 
- *
- * Usage notes:
- *
- * Due to cross browser flakiness, there are many many limitations on what is
- * possible in terms of dragging and dropping to DesignMode enabled iframes.
- *
- * To make this work, your "droppable" elements must be image tags.  No ifs, ands, 
- * or buts:  image tags have the best cross browser behavior when dragging.
- *
- * When DnD is initialized, it begins timers which periodically check your 
- * editor iframe.  If an image is dropped in, DnD takes the element and 
- * attempts to parse it for a unique ID which you can use to do a lookup for 
- * an "editor representation."  If an editor representation is found, 
- * typically the image is replaced with the representation snippet, but you are
- * free to do whatever you want.
- *
- * Because of browser limitations, the safest way to parse the element is to
- * look at the img's src attribute and use some or all of the image URL. 
- * In my experience, the best way to deal with this is simply to parse out
- * generate a query string in the src attribute server side that corresponds 
- * to the proper representation ID.
- *
- * If the target is not an iframe but a textarea, DnD provides a very minimal
- * system for clicking what would otherwise be dragged to insert markup into 
- * the textarea.
- *
- * DnD is purely a utility library:  to make it work for any particular editor,
- * CMS, etc:  It is very unlikely it will provide much benefit out of the box.
- *
- * Because DnD spawns so many timers, they are stored in a $.data element 
- * attached to the parent document body.  Implementers should consider clearing
- * the timers when building systems such as dynamic searches or paging 
- * functionality to ensure memory usage and performance remains stable.
