/* 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
