Opt-in support for command execution

[henke37]

An obscure feature of ass files is that they can execute os level commands. This is obviously impossible and/or a huge security vulnerability on the web.

But why not allow the user to provide a callback that can handle commands as they please? Sorta like the ExternalInterface system the flash player used. This way advanced users can provide whatever support they like for all sorts of nonstandard effects.

What is your use case? Given that desktop renderers (libass, VSFilter) ignore Command events, I doubt anyone is writing a general-purpose script that has them.

I have no usecase.

I don't think it's worth implementing it then.
