Sub-widget approach on SpinButton limits sensible theming options

It should be possible to let the entry cover the whole widget area visually, to then draw up/down arrows inside of it. In any case, focus indication should be allowed to affect the whole widget, not just the entry part. For example drawing a colored rectangle around it all.
