Batik 1.6 - NPE in with getStyle or getPresentationAttribute methods

[Rick Bullotta]

With Batik 1.6, we're encountering an NPE when trying to use these
methods.  

The common issue seems to be related to:

        CSSEngine eng =
((SVGOMDocument)getOwnerDocument()).getCSSEngine();

...which is in the source for both these methods.  I suspect that in
some cases, this may be returning null?

Any insights?

Hi Rick,

    Well you get this when you haven't booted the CSS engine.
There is an example of how to do this on the Wiki.  I don't
think this is anything that has changed in 1.6.
