changed to ignore labels below the top level of hierarchy. This
turned out to be a bad idea. However, the original behavior was
problematic due to confusion over what part of the hierarchy the
labels were in. The new behavior prefixes each label with the
cell hierarchy, eliminating both problems. (2) Corrected the
problem where the attachment box for rendered labels is not
displayed if the label name is not in the viewing area. (3)
Corrected the problem where redirection of input from the layout
window to the console window with the ":" command gets inadvertently
canceled; this turned out to be due to a missing "*bypass" in
front of the command that finds the output scale to display the
pointer coordinates, and this was happening whenever the mouse was
moved while typing in a command.
