shadowFrustumSize
version 25
设置渲染阴影贴图的视椎的大小，用于配置解决某些角度下阴影被裁切的问题，并不是越大越好，以刚好能够包裹需要展示阴影效果的场景为宜。建议范围为（500 - 10000），依据场景的size和光的方向来调试确定，不配置的话默认值为"2000, 2000"
sample:
"shadowFrustumSize": "2000,2000"
shadowMapSize
version 25
阴影贴图的分辨率（决定阴影的精细程度），字段的值的提供形式为字符串，分辨率的宽、高使用逗号隔开，建议范围为"128,128"至"1024,1024"，不配置的话默认值为 "1024,1024"
sample:
"shadowMapSize": "256,256"
