#include "e.h"
/* TODO List:
*
* * support change of menu items after realize
* * support add/del of menu items after realize
* * support text/color classes
* * refcount menu up while looping thru and calling other fn's
* * support alignment (x, y) as well as spawn direction
* * need different menu style support for different menus
* * add menu icon/title support
* * use event timestamps not clock for "click and release" detect
* * menu icons can set if/how they will be scaled
* * support move/resize of "box" that spawned the menu
* * add image item (label is replaced by image/icon)
* * add generic evas object item type (label replaced by object)
* * allow menus to stretch width/height to fit spawner widget/box
* * allow menus to auto-shrink (horizontally) if forced to
* * support auto left/right direction spawn
* * support obscures to indicate offscreen/not visible menu parts
