wm4 2e66f4b89b video/out: do remaining config to reconfig replacements 
The main difference between the old and new callbacks is that the old
callbacks required passing the window size, which is and always was very
inconvenient and confusing, since the window size is already in
vo->dwidth and vo->dheight.
