Summary:
Some ecore_evas such as ecore_evas_extn_plug doesn't have evas.
ecore_evas_extn_plug seems to be Ecore_Evas, but actually it is Evas_Object_Image.
ecore_evas_extn_plug makes new ecore evas, but it only exists to communicate with ecore_evas_extn_socket.
newly ecore evas only open and close file(ecore_evas_extn_socket). so it doesn't have evas.
```
EAPI Evas_Object *
ecore_evas_extn_plug_new_internal(Ecore_Evas *ee_target)
{
...
ee = calloc(1, sizeof(Ecore_Evas));
...
o = evas_object_image_filled_add(ee_target->evas);
...
return o;
}
```
