This class extends IntegerPropertyBase and provides a partial
implementation of a StyleableProperty. The method
StyleableProperty.getCssMetaData() is not implemented.
This class is used to make a javafx.beans.property.IntegerProperty,
that would otherwise be implemented as a IntegerPropertyBase,
style‑able by CSS.
