Unfortunately, QuickTime doesn't link against the same CoreVideo that we would,
so there's a similar situation there to the CF one.

The only remaining issue is one of constants defined in CoreVideo headers. 
Right now, we're doing things like: 
    if (buffer.pixelFormat() == kCVPixelFormat_32ARGB).  
We could convert those checks into things like: 
    if (buffer.pixelFormatIs32ARGB())
...and be in the clear there too.
