using elm_widget_focus_direction_go function, focus will be moved from
the current focused object to the near object in one direction.
Direction can be set by degree(for easy usability). Degree changes
clockwise, i.e. 0 means UP, 90 means RIGHT, 180 means DOWN, and 270
means LEFT. You can select any direction by changing this degree.
