There is a similar (or may be worse) problem in  Should that
paragraph then read: "... If a node is skiped by the active whatToShow
flags, a Filter will not be called to evaluate that node. ..."?   The
problem here is, that the children of that node would be evaluated
even if the Filter would have rejected the node, if it had been
called.  Since rejecting, which is a possible result in using a
filter, is something stronger than skipping it seems to me more
natural to apply a Filter before applying whatToShow flags.
