My apologies, but it turns out the two-GUI issue was a false alarm.

The only explanation that seems reasonable is there must have been
some stale files hanging around in the build tree that caused this
issue because when I started with a fresh build of master tip as the first
step of git bisect, the issue was completely gone.  Furthermore,
the zoom issue was gone as well.  And I also get the same good results
(again starting with a fresh build) for commit afd37a9 (the one I used
for my series of wxwidgets tests).

I am virtually positive that unlike the two-GUI issue, the zoom issue
was not a false alarm because Andrew saw this zoom issue, and I
confirmed it as well several times using a fresh build, so I think
what happened there was one of the recent plbuf fixes prior to afd37a9
fixed it.  But I am not going to investigate further, and will happily
take this good master tip result!

So the current release status is we are still in deep freeze following
the rule of thumb I expressed to Phil (with the addition that all
documentation changes are still allowed), but master tip is
considerably higher quality than I thought with no known rendering
regressions.  Of course, there is still a lot of work to do to finish
this release, but I am happy with where we are at the moment.

So the only topic left in this subthread discussion that I am aware of
is the authorization issues discovered by Phil when attempting to
verify the (irreproducible) two-GUI issue, but I assume that is a
local platform issue for him that he will be able to straighten out.

@Phil:

On that topic, I have just noticed now that Debian has installable
packages for both Tcl/Tk 8.4 and 8.5 so I assume Ubuntu supplies those
as well. So if your cmake output shows cmake is finding Tcl/Tk 8.4,
that is probably the source of your authorization issue, and to solve
it you must install Tcl/Tk 8.5.  If that doesn't solve the issue, then
you should check what your current default version of tclsh is using
the following pattern of commands.

irwin@raven> ls -l /usr/bin/tclsh
lrwxrwxrwx 1 root root 23 Sep 29  2012 /usr/bin/tclsh -> 
/etc/alternatives/tclsh*
irwin@raven> ls -l /etc/alternatives/tclsh
lrwxrwxrwx 1 root root 22 Aug 10  2014 /etc/alternatives/tclsh -> 
/usr/bin/tclsh-default*
irwin@raven> ls -l /usr/bin/tclsh-default 
lrwxrwxrwx 1 root root 8 Mar 19  2013 /usr/bin/tclsh-default -> tclsh8.5*

If that symlink trail leads you to tclsh8.4, then you must run the
update-alternatives command appropriately to change that symlink trail
so that tclsh refers to tclsh8.5 and similarly for wish.
