Since this change, instead of getting pseudo randomly (in decreasing 
probability order) VLC to:
- create a non-embedded video output window,
- fault memory segmentation, or
- create an embedded video output smaller than a post stamp,
I get VLC to consistently create non-embedded video output window.

To me, there is no question that the current situation is better, not only 
from an software engineering perspective, but also from an usability one.

The problem is well known - total insane lack of thread synchronization when 
allocating the window, causing a segmentation fault, or a denial of feature, 
depending on how far the interface object has been initialized at the time of 
creating the video output.
