transform tools' preview should take linked-group in consideration

Submitted by Jakub Steiner Link to original bug (#112859)
Description
As a new and awesome feature, GIMP can apply transofrmations on a group of linked layers. However the transform tools only show a preview grid for the active layer, not the whole group.
It would be visually more appropriate to show a grid that would encompass the whole area all the layers in group take.
