- Implement DDE from wine. Leaving debug errors on the run and later move to trace. See CORE-7447.
- Use callbacks to User32 to convert the data and track it in Win32k.
- Add a new Quality of Service atom.
- Add things to class.c.
- Shell32 tests run now too, or only 4 run. This might be fixed too, since locating a lParam write back issue.
