Prowling around the IDE scripts, the revBackScript button of the revLibrary

My understanding of the message path is that since this is in a back
script, the only other place for that message to go is to the engine. Is
that right?
All backscript and library handlers are available to all other
backscripts and libraries.
The only time their specific order comes into play is when dealing with
handlers of the same name in two different scripts. In that case,
libraries are checked first, and then backscripts, in the order in which
they were inserted into the message path.
Additionally, "dispatch" has an unusual characteristic that's not likely
at play here, but worth knowing about: if a custom message sent with
dispatch isn't handled, you won't get a "handler not found" error as you
would with "send". Instead, the local var "it" will simply contain
"unhandled".
