强制解析抗锯齿渲染纹理。
If an antialiased render texture has the bindTextureMS flag set, it will not be automatically resolved. Sometimes, it's useful to have both the resolved and the unresolved version of the texture at different stages of the pipeline. If the target parameter is omitted, the render texture will be resolved into itself.
