'''Disable updating any traits automatically due to changes in VTK.
Specifically, do not auto-update *any* objects due to the firing of a
ModifiedEvent from within VTK. This basically can call `update_traits` on
the object which can in turn fire off other callbacks.
Use this sparingly when you REALLY need to disable updates.
