I don't think Core Image is properly supported yet in RubyCocoa
(please correct me if I'm wrong). I seem to remember somebody else
having a go at getting it to work a while back...
I think arbitrary structs are not supported. However, since CGRect is
structurally the same as an NSRect you can probably get away with
this (untested):
