/**
*
* <p>The `Graphics` module provides a JavaScript API for creating shapes in a variety of formats across
* a <a href="http://developer.yahoo.com/yui/articles/gbs">browser test baseline</a>.
* Based on device and browser capabilities, `Graphics` leverages <a href="http://www.w3.org/TR/SVG/">SVG</a>,
* <a href="http://www.w3.org/TR/html5/the-canvas-element.html">Canvas</a> and <a href="http://www.w3.org/TR/NOTE-VML">VML</a>
* to render its graphical elements.</p>
*
* <p>The `Graphics` module features a <a href="../classes/Graphic.html">`Graphic`</a> class that allows you to easily create and manage shapes.
* Currently, a <a href="../classes/Graphic.html">`Graphic`</a> instance can be used to create predifined shapes and free-form polygons with fill
* and stroke properties.</p>
*
* <p>The `Graphics` module normalizes an API through the use of alias and implementation classes that share
* interfaces. Each alias class points to an appropriate implementation class dependent on the browser's
* capabilities. There should rarely, if ever, be a need to interact directly with an implementation class.</p>
*
* <p>Below is a list of available classes.
* <ul>
* <li><a href="../classes/Graphic.html">`Graphic`</a>
* <li><a href="../classes/Shape.html">`Shape`</a>
* <li><a href="../classes/Circle.html">`Circle`</a>
* <li><a href="../classes/Ellipse.html">`Ellipse`</a>
* <li><a href="../classes/Rect.html">`Rect`</a>
* <li><a href="../classes/Path.html">`Path`</a>
* </ul>
* You can also extend the `Shape` class to create your own custom shape classes.</p>

* After instantiation, a shape or segment needs to be drawn for an element to render. After all draw operations are performed,
