Global prefix config for keyframes

[asins]

I set @ms : false;

But I still will be generated - o - content e.g.

.keyframes(~'lightSpeedOut, 0% {transform: translateY(0%) scale(1); opacity: 1 } 100% {transform: translateY(5px) scale(.9); opacity: .4 }');
to
@-o-keyframes lightSpeedOut {
    0% {
        -o-transform: translateY(0%) scale(1);
        opacity: 1
    }
    100% {
        -o-transform: translateY(5px) scale(.9);
        opacity: .4
    }
}
...

It's opera prefix. You will need set @opera_local: true;

You can set @opera: false for globally disabling opera syntax or @opera_local: false for disabling opera syntax only for the keyframes.
