This example shows how to create gradient fills for a shape. By default, the <code>fill</code> attribute of a shape instance will generate a solid fill for the shape. Setting the <code>type</code> property on the <code>fill</code> attribute to <code>linear</code> or <code>radial</code> will create corresponding
gradient fill. Each gradient type has its own set of properties for defining the fill. Both share the <code>stop</code> property. The <code>stop</code> property defines the colors and their opacity and position in a
gradient fill. It is an array of objects containing the following information.
</p>
<dl>
<dt>color</dt><dd>The color of the stop.</dd>
<dt>opacity</dt><dd>Number between 0 and 1 that indicates the opacity of the stop. The default value is 1. Note: No effect for IE <= 8</dd>
<dt>offset</dt><dd>Number between 0 and 1 indicating where the color stop is positioned.</dd>
</dl>
<p>
Linear gradients included a rotation property which defines the direction of the gradient. (by default, linear gradients go left to right)
<dl>
<dt>rotation</dt><dd>Linear gradients flow left to right by default. The rotation property allows you to change the flow by rotation. (e.g. A rotation of 180 would make the gradient pain from right to left.)</dd>
</dl>
</p>
<p>
Radial gradients include the following additional properties:
<dl>
<dt>cx</dt><dd>The x-coordinate of the center of the gradient circle. Determines where the color stop begins. The default value 0.5.
<p><strong>Note: </strong>This property currently has no effect on Android or IE 6 - 8.</p>
</dd>
<dt>cy</dt><dd>The y-coordinate of the center of the gradient circle. Determines where the color stop begins. The default value 0.5.
<p><strong>Note: </strong>This property currently has no effect on Android or IE 6 - 8.</p>
</dd>
<dt>r</dt><dd>Radius of the gradient circle. Determines where the color stops end. The default value is 0.5.</dd>
<dt>fx</dt><dd>Focal point x-coordinate of the gradient.</dd>
<dt>fy</dt><dd>Focal point y-coordinate of the gradient.</dd>
</dl>
</p>
