If someone built an application against libvlc 0.9.2, it should still work 
against libvlc 1.0.0 without recompilation. That's called ABI backward 
compatibility. Without this, we get into "DLL hell".

I fail to see why snapshot support could not be done while retaining backward 
compatibility for applications that don't use snapshots.
