 I need to destroy the vout display when the size changes, so I am not sure to
see what you would do.
 Besides, this way also make vout reuse for win32 works without any work at all.

Therefore vout (and aout) should be parented statically to the input manager (playlist, libvlc media player or vlm), I believe. Then reparenting is not needed.
 This commit didn't change the parenting behaviour...
 Anyway, before changing the parenting behavior, I need to change/fix a
few things (SPU, configuration, input_thread reference, etc).
