This was not implemented in the first version of snapshot since it relies upon Image Ops which was just completed. Now that Image Ops is in, the snapshot API will need to be slightly modified. The parameter and return value of the 4 snapshot methods will change to taking a WritableImage subclass of Image, both for type safety, and in order to implement updating an existing image in place.
