Description

If the xlink:href attribute on a gradient points to a non-existent element, an NPE is thrown when rendering.

For example:

<radialGradient id="MyGradient" xlink:href="#Nonexistent">
<stop offset="0%" stop-color="green" />
<stop offset="50%" stop-color="blue" />
<stop offset="100%" stop-color="red" />
</radialGradient>
