I stand corrected.  I had to add a bit to allow for the arrows.
Unfortunately, since SpinButton is an Entry, I can't just set the usize of
the Entry and get the right result.  This hack won't work right with other
themes, I'm afraid.

I have the exact same problem with GtkMenu, it doesn't like to resize
itself to accomodate longer items (even when prompted with
gtk_widget_queue_resize()).  Instead I find the longest item and set that
as usize, adding a but to allow for border and handle.  Not a pretty sight,
but better.
