evas/image - update dirty region in the render time.

evas/image - update dirty region in the render time.

this fixes the proxy rendering that sub object of the source couldn't be dirty region set.

since the object could be invisible nor won't be pre-rendered neither.

Im supposing the mapped(proxy) object rendering sequence should be totally refactored

that should be separated with the normal rendering sequence.

Until that, this change will be alternative solution.
