Returns info to update the window size, keeping non-0 collapsed frames the same pixel size IF possible. Never returns an error.
This sacrifices the min (percentage) size of other frames if needed, although not to the point of making them 0 size (which would break the layout).
If there is absolutely no space, it will leave things as they are. This just means that the collapsed frame will shrink further than your ideal pixel width, but percentage size will stay the same.
