I did not spend any time thinking about generalizing code, but I guess
it would certainly make sense to merge the image diffing or even the
glade file => cairo surface containing snapshot code. So if you need
something like that, better generalize it then copying it or inventing
your own nefarious scheme.

What is a "frequently run" test? I can tell you that no treeview test
qualifies as "frequently run" to me when I'm hacking on GtkPaned. And
I think the same applies to you vice versa. Which reduces the
"frequently run" tests to a number very close to 0 I guess.

However, if the tests will still live under gtk+/unittest/ and are part of the default full build, then this might not be that big of a problem.
I've heard that argument before and the only response it got from me
was a confused look. Testsuite code is run regularly by make distcheck
and buildbots. If you add to this the fact that the code will keep
running unmodified until we break API again, this argument quickly
stops making any sense. At least to me. So building tests only as part
of make check (like everyone else does) seems like a very sound thing
to do, in particular for code as stable as GTK.

I would personally move testgtk and friends into demos/tests/ but I
don't care either way. I guess Matthias is the one that gets to decide
