UI: show gizmo while transforming

When interacting with translate/rotate/scale gizmo, show the gizmo while
it's in use. There are some exceptions to this, as showing all scale
gizmos while scaling causes the gizmos to become large & distracting so
in this case only the gizmo being dragged is shown.
