You're quite right, 'whiteout and 'layer are grob properties so they
apply to all elements of a grob's stencil.  I confess I don't know
exactly what you are trying to do here, but I'm not sure whiteout
is a good approach, even if it worked.  Can you not draw the bar
line differently for this special case rather than whiting-out parts
of it?
