OK, I see what you mean now, and I'll make that change in version 2 of
this patchset.

As always, you can see my most up-to-date work at
<https://github.com/alexhenrie/wine/commits/master>.

Andrew: Don't bother signing off any of these patches. Just tell me if
you want timelineobj.c merged into timeline.c, and any other comments
you have. After that I will resubmit all 5 patches with the new tests
etc. that Nikolay suggested.
