I've decided to keep the interface instead of using the struct directly, since it'll be easier to use the interface functions for transformations and other paramaters. Referencing the interface via the object for every function call seems a bit redundant. Also I think refcounts should be handled seamlessly this way.

A reference to the background material created internally is also kept here. As Stefan had pointed out, the material is not AddRef'd since its handle is used instead, so it's probably safer to keep the reference to ourselves and release it when the object is destroyed.

Cheers,
