This should be up to the plugin. I can't think of a good interface right 
now given that we don't have enough examples to look at and learn from. 
Personally, I'm just signaling a semaphore before the callback and have 
the image "pull up" the arguments via primitives. This avoids the need 
to do too much at the primitive level.
