按照教程实施一个最简的动态图集示范：

        const atlasManager = new Laya.DynamicAtlasManager({
            largeTextureSize: [1024, 1024],
            maxLargeTextures: 2,
            textureUnitSize: 16,
            extendSize: 1,
            immediately: true, // true或false都会产生相同错误
            autoExtend: true,
            checkDuplicate: true
        });
        const url = "resources/layaAir.png";
        Laya.loader.load(url).then((res) => {
            atlasManager.addTexture(res);
        });

出现错误：

WebGL2DRenderCMD.js:69 Uncaught TypeError: Cannot read properties of null (reading '_textures')
    at WebGLBlit2DQuadCMD.apply (WebGL2DRenderCMD.js:69:44)
    at WebglRenderContext2D.runOneCMD (WebGLRenderContext2D.js:73:13)
    at CommandBuffer2D.applyOne (CommandBuffer2D.js:67:47)
    at LargeTex.onUpdate (LargeTex.js:50:28)
    at LargeTexManager.onUpdate (LargeTexManager.js:104:34)
    at LargeTexProcessor.update (LargeTexProcessor.js:81:15)

LargeTex._drawTex中，只创建了一个 Blit2DCMD，而SetRendertarget2DCMD完全没有被调用，导致_destRT永远是null。
