Does anyone know of a Gaussian Blur plugin which works in XaraXtreme, which gets the same result as the PhotoshopCS Blur plugin?

I'd like to blur a shape and the XaraXtreme's inbuild feather region tool is not 'preceise' enough for what i'm looking for.

Are there any Photoshop Blur plugins which work in XaraXtreme?

Thanks for your advice!
