I managed to add some functionality to update tags into database but there are 2 things that bother me:
1. There is a method in utilities/facemanagement/facegroup void FaceGroup::applyItemGeometryChanges() that add garbage tags into database when image is rotated... I disabled this line
            //d->editPipeline.editRegion(d->info, d->view->previewItem()->image(), item->face(), currentRegion);
but I'm not sure if it doesn't affect something else.

2. As far as I understood, there is some lazy algorithm for displaying tags rectangle on a image... the problem is if I will try to hover the photo while it still rotate, tags won't be displayed correctly...I set a hover lock but it doesn't seem to work...
