The reson why I add this is for communicate with X in async mode.
For example, If applications call elm_win_rotation_with_resize_set API
when they start run and rotation mode is set.
ecore size doesn't changed yet, so it make elm window size to 1
becaues elm window's resize function use ecore_evas_geometry_get API.
so I add new api help upperside get info related with recently request geometry
