Step size for objects with sizing restrictions.
This is not a size enforcement in any way, it's just a hint that should be used whenever appropriate.
Set this to for an object to scale up by steps and not continuously.
Efl.Ui.Win.hint_base + N x Efl.Ui.Win.hint_step is what is calculated for object sizing restrictions.
Since 1.22
@property hint_step { get {} set {} values { sz: Eina.Size2D; } }
Eina_Size2D efl_ui_win_hint_step_get(const Eo *obj); void efl_ui_win_hint_step_set(Eo *obj, Eina_Size2D sz);
