* The panes widget adds a draggable bar between two contents. When dragged
* this bar will resize contents' size.
*
* Panes can be displayed vertically or horizontally, and contents
* size proportion can be customized (homogeneous by default).
*
* Smart callbacks one can listen to:
* - "press" - The panes has been pressed (button wasn't released yet).
* - "unpressed" - The panes was released after being pressed.
* - "clicked" - The panes has been clicked>
* - "clicked,double" - The panes has been double clicked
*
* Available styles for it:
* - @c "default"
*
* Default content parts of the panes widget that you can use are:
* @li "left" - A leftside content of the panes
* @li "right" - A rightside content of the panes
*
* If panes are displayed vertically, left content will be displayed on
* top.
*
* Supported elm_object common APIs.
* @li @ref elm_object_part_content_set
* @li @ref elm_object_part_content_get
