I also should have mentioned that each app ported is another test case
for xcb to help us find/fix bugs, and another bit of sample code for
others to reference.

Well, as noted in my original list, I see a lot that just don't make
sense to port or aren't worth the effort, like most of the libXaw programs,
so I'm sure there will be plenty around for a while.   So far the ones
we've ported (x*info / xls* type apps) are atypical clients, not really
serving as good examples/tests of what a normal app does (none of them
even open a window for starters).

And the specific test suite apps (rendercheck, x11perf, XTS) it makes
sense to explicitly keep libX11 code around, even if we make it a
build time configuration, so that we can continue to use it to test
libX11.
