Oversight in 4bede1b555
`transformApply` / `transformEnd` already gives us a `NC_MASK |
NA_EDITED` notifier (via `viewRedrawForce`), so listen to that in
`image_main_region_listener`.
NOTE: alternatively, we could send an appropriate notifier in
`special_aftertrans_update__mask` (or remove the condition from the one
that is already there), with the difference that the gizmo would only
update after the transform is confirmed -- which may or may not be
desired
