Browserless fullscreen retain size of controls

Hello all!

I’m throwing together a small image viewer like that at
creativity online,
that has a full screen option. I’ve got all elements nicley in place, but my final problem is with retaining the size of the control bar (you’ll see with creativity online…like youtube, etc., the navigator controls stay the same size).

I’ve set it up so that all of the elements decrease by half size for now, but it’s not a good forever solution.

Any ideas?
