[jsr-314-open] begin success complete and rendered?

[Jim Driscoll]

You know, that's a really good question - I don't think we considered 
that use case.  Probably because we were expecting the rendering process 
itself to not take a really noticeable amount of time.    Other than 
rendering a new image component, or a complex canvas, or a really 
complex table, I can't imagine it taking all that long - what are you 
rendering?

(If it's just a single image tag that's rendering, you could always do a 
onload attribute on that element...)

Though I haven't tested it, I think that a rendered event isn't going to 
help you anyway if it's an image, since the image itself will be loaded 
out of band (I think) after the DOM is updated, and the rendered event 
will have long before fired off...  more or less mimicking what you're 
already seeing.
