Just wanted to add: I checked what the behaviour was in Win32, a WM_PAINT msg
was send to the application, so that checks out. The UpdateWindow() api @ msdn
indicates one should see direct result, which is reflected in the default Wine
behavior on these same-thread commands. And since I didn't want to change too
much in other functions, I decided to add it to update_now() since that's
already singled out for solely serving UpdateWindow(). I do however think it
might be best for the sake of keeping things together and sane, the
USER_Driver->pMsgWait... line should be inside the (flags & RDW_UPDATENOW) IF
statement at the end of RedrawWindow().

Anyway, I leave it up to you guys to decide.
