Bastien Bouclet 94344ccf8e GUI: Allow providing an explicit size for screen_center dialogs
Without an explicit size the layout system does not have enough
constraints to produce nice looking dialogs. Up until now the workaround
was to set explicit an size for some of the widget. This worked well
enough except when resizing down the window up until the widget size
constraints could no longer be enforced. At that point, produced layouts
looked too squished.
