Changes in the source projection are currently not supported. It would
cause the exact same issues we have with restarting a vout (because the
one used may not be the correct one, on Win7 for example a D3D9>OpenGL
switch is needed) and it would break the direct rendering in use.
The PAR/SAR are just metadata that are supported dynamically by all vout
that support direct rendering. If they don't support DR it would be OK
to recreate them.
So the real issue is to support the dynamic source change properly when
DR is used. Some properties are easily handled, some are not.
