GimpSpinButton is a drop-in replacement for (and a subclass of) GtkSpinButton. Unlike GtkSpinButton, it avoids updating the adjustment value when losing focus, unless the entry text has changed. This prevents accidental loss of precision, when the adjustment value can't be accurately displayed in the entry.
