back 17 years ago, no no need to carry them in public interface any longer.

This header has now become obsolete. There're also no external consumers
(drivers, etc) left, so it now finally can be dropped entirely.

Not used by any external module (eg drivers), so no need to keep it
exported. Also documenting it.

The symbol isn't exported, thus not accessible to modules.
No need to keep it in public header.

Unlikely to practically happen, but still safer to just check for sure.
A simple zero-value test doesn't cost us much (on modern CPUs perhaps
not even a full clock cycle).

Since GetPictureScreenIfSet() explicitly can return NULL, better be
prepared for that to happen (instead of hard crash)

Even if those situations shouldn't practically happen, it's better to have
some sanity checks just in case.

Even though it shouldn't practically happen, better adding a trivial check,
just in case. The check is really cheap and possibly optimized-out.

Even though it practically should never happen, but just in case, and
for silencing the analyzer, add an extra check here (which doesn't
cost us much).

Reduce the analyzer spam a bit by adding some extra asserts.
Since it's test code, we can't have enough of them anyways ;-)

Adding a little bit more logging to the startup process, eg. telling

Even though it probably won't be hit ever, it's still better to be
