Fix resize of top frame not updating scaled pixmap
* Also limit viewing features such as zoom levels when files have different dimensions * GraphicsViewImageViewer is still a bit buggy: the scrollbars are toggled on when the pixmap is null in the reference viewer (we do not use that class right anyway)
