Damn.. no wonder why i didn't find it. Are you sure about this? Cause widgets and other stuff can be resized.. It sounds strange to hard code something like that. I was thinking it might be possible to edit it through gconf in some way and as i have no experience at that.. was not able to find it.

So the only way to accomplice this is to use Queen Beecon. Hope someone make an easier way to do this. It would be awesome to configure this and other items.
