The need to re-subscribe to requestAnimationFrame

[David Bruant]

Hi,

If someone wants to reuse the same function for 
requestionAnimationFrame, he/she has to go through:
    requestAnimationFrame(function f(){
        requestAnimationFrame(f);
        // do stuff
    })
I was wondering why it was the case. Other event-like mechanism do not 
require to re-subscribe after an event happened.

Thanks,

David
