+ *  although they may in reality be the same. This is an unfortunate but
+ *  necessary speed concern. Use Mix_QuerySpec() to determine if you can

+ *  effects run on a given channel before any other mixing occurs. These

+ *  their Mix_EffectDone_t function called when they are unregistered (since
+ *  the main output stream is never "done" in the same sense as a channel).
