laya-coreui-es/build/es/layaAir/laya/webgl/shader/d2/value/PrimitiveSV.js

laya核心库、ui库es版本，剔除了媒体、TTF等功能。基于 LayaAir-release_2.12.0 修改

import { Value2D } from "./Value2D";
import { ShaderDefines2D } from "../ShaderDefines2D";
export class PrimitiveSV extends Value2D {
    constructor(args) {
        super(ShaderDefines2D.PRIMITIVE, 0);
        this._attribLocation = ['position', 0, 'attribColor', 1]; 
    }
}
