Circle scroller is based on elm_scroller and is scrolled by rotary event.
Circle scroller is to visualize and utilize scroll effect for elm_scroller. While elm_scroller provides scrollbar with straight horizontal/vertical movement, circle scroller provides scrollbar with circular movement. Rotary event can be activated by eext_rotary_object_event_activated_set(), circle scroller scrolls items upward/leftward responding to counter clockwise rotary event, and scrolls downward/rightward responding to clockwise rotary event.
The available circle object items are as follows:
"default"
: Default circle item. It draws vertical scroll bar."vertical,scroll,bg"
: Vertical scroll background circle item."horizontal,scroll,bar"
: Horizontal scroll bar circle item."horizontal,scroll,bg"
: Horizontal scroll background circle item.
