Unfortunately I think this is buggy for deallocate.
Since _view's dimensions are changed after recreated, you can't get the
original capacity from the changed dimensions.

Capacity must be kept to make deallocate right.

BTW, I've made my own image type which accepts align as a template param
instead.

Thanks
