I tried this and because I was trying to pass additional arguments the
compiler complains.
In practice, however, other (similar) function types are also cast to
Icallback. They mostly have a different number of parameters. For instance
the callback of a canvas for the RESIZE_CB has the structure:

So if I had to call the resize call back how would I pass in the width and
height arguments?
Thanks,
Milind
