WebGLFramebuffer 接口时 WebGL API 的一部分，它提供了一个缓冲区的集合，这些缓冲区可以作为一个整体用作渲染操作的目标缓冲区。
摘要
WebGLFramebuffer 对象的内容不能直接访问，因此该对象没有定义任何用于操作其自身内容的方法和属性。需要使用 WebGLFramebuffer 对象时，请使用 WebGLRenderingContext 对象的以下方法：
WebGLRenderingContext.bindFramebuffer()WebGLRenderingContext.createFramebuffer()WebGLRenderingContext.deleteFramebuffer()WebGLRenderingContext.isFramebuffer()
示例
创建一个帧缓冲
var canvas = document.getElementById('canvas');
var gl = canvas.getContext('webgl');
var buffer = gl.createFramebuffer();
