have a shutdown routine that deletes all objects, structures etc. associated
with a evas canvas then sets them all up again without destroying the
ecore_evas? u can just get the bottom most evas object in the canvas and keep
deleting the bottom object in a loop until there is no bottom object... (empty
canvas) :)
ie
while ((o = evas_object_bottom_get(evas)) evas_object_del(o);
will completely clear all objects in a canvas and empty it out completely.
