It should be possible to make Dialog respect its parent

[Daniel d'Andrada]

In the future unity8 will rotate instead of having apps rotating themselves. So that launcher, edge gestures, panel and application UI all have the same orientation and rotate together nicely. This includes the dialogs shown by unity8, such as the power dialog that pops up when you long-press the power button.

This is unity8's hierarchy:

// the root item
OrientedShell {

    // the actual Shell UI, which gets rotated
    Shell {
        rotation: someAngle

        Loader {
            Dialog {
            }
        }
    }
}

So we need the Dialogs to keep their parents so that they carry on the transformations applied to Shell, instead of being a sibling of it. This should be simple to accomplish as Dialog is an Item, and items are expected to respect their parents instead of reparenting themselves. So I'm just asking Dialog to *do less*.

Dialog is an Item and thus inherits its public API. Items have a parent property that is free for the user to manipulate it. Dialog should respect it.

Otherwise we will have to poke into Dialogs private API to achieve that, which is a fragile approach as that can break at any future release without warnings. Another bad option would be forking Dialog code, copying it over to unity8 code base (as we already do for the splash screen feature).

adding to canonical-devices-system-image as we would need this bug fix to land along with any shell rotation work.

  [ Daniel d'Andrada ]
  * This is needed by unity8 for the "shell rotation" feature (ie
    shell does all the rotation work instead of apps rotating
    themselves). unity8's dialogs (like the power dialog when you
    long press the power button) should follow its parent item
    rotation and size, as one would expect, and not be sneakily
    reparented to the scene root item, in which case the shell
    UI would be rotated but its dialog would not.
