[wp-hackers] Plupload, WP 3.3 and client-side resizing

I am currently searching for documentation about the Plupload script
that was integrated into the WP core with the 3.3 release.

My needs are the following:

- force a size limit of 1024px width / height for picture uploads.
- if the picture is bigger, ask the browser for client-side downsizing.
- if the browser can't do it, refuse the upload and provide a
meaningful error message.

I was wondering if WP 3.3 would provide a config panel for such
settings, a bit like the (now obsoleted) WPlupload plugin did:

Or can we define such things in functions.php ? Is there any
"official" documentation about how Plupload works in WP? Any examples
or "best practices"?

Many questions. For some reason, Google didn't bring up any up-to-date

Any advice would be much appreciated.
