the atlas the regions are read from
Optionaldisabledthe region drawn while disabled; normal at half opacity if left out
Optionalhoverthe region drawn under the pointer; normal if left out
Optionalinsetxthe width of a corner kept unscaled, in pixels; a quarter of the region's width by default
Optionalinsetythe height of a corner kept unscaled, in pixels; a quarter of the region's height by default
the region drawn at rest; also sets the button's default size
OptionalpressedThe region drawn while held down; normal if left out. When it is
shorter than normal, as pressed art usually is, it is drawn lowered
by the difference and the label moves down with it.
The art of a skinned UITextButton: one atlas region name per state, plus the
atlasand optional nine-slice insets from UISkin.Each region is drawn as a nine-slice, so the button can be any size. Every region named is looked up when the button is built, so a typo throws there.
