# NOTE: We do a plain-old reparentTo here (non-wrt)
# under the assumption that the node has been
# positioned as if it is already under the new parent.
#
# The only case that I can think of where the parent
# node would not have been registered at the time of
# the reparent request is when we're entering a new
# zone and manifesting remote toons along with
# other distributed objects, and a remote toon is
# requesting to be parented to geometry owned by a
# distributed object that has not yet been manifested.
#
# (The situation in the factory is a little different;
# the distributed toons of your companions are never
# disabled, since the toons are in the factory's uberzone.
# They send out requests to be parented to nodes that
# may be distributed objects, which may not be generated
# on your client)
#
# It is therefore important for that remote toon to
# have his position set as a required field, relative
# to the parent node, after the reparent request.
# If the node has already been registered, the toon will
# be in the correct position. Otherwise, the toon will
# have the correct position but the wrong parent node,
# until this code runs and corrects the toon's parent
# node. Since we don't start rendering until all objects
# in a new zone have been generated, all of that action
# will happen in a single frame, and the net result will
# be that the toon will be in the right place when
# rendering starts.
