[vtkusers] Apply one transformation matrix to an other actor

[David Cole]

Try GetMatrix / SetUserMatrix. If the destination actor has any position,
rotation or scaling directly, you'll have to reset those to 0 or 1
appropriately. If not, the destination actor should snap to the source
actor after calling SetUserMatrix.
