evas_render: add restacked mapped obj to redraws rect
Summary:
We are adding A object area to the redraws rect when object stack is changed
from (1) to (2) if A object is not mapped.
(1)
┌────────┐
│Object A│┐
└────────┘│
└────────┘
(2)
┌────────┐
│┌────────┐
└│Object B│
└────────┘
But if A object is mapped, then we are adding only part of A object area.
(part of A)
┌────────┐
│┌───────┘
└┘
So the result of stack change is (1) not (2).
This patch set is adding restacked mapped object to the restack_objects array,
after changing the stack of mapped object to add correct redraws rect.
