glRenderbufferStorage — establish data storage, format and dimensions of a renderbuffer object's image

有点像descriptor

bind前后用 sample

 //渲染缓冲区作为颜色缓冲区

 glGenRenderbuffers（1，& colorBuffer）; 

 glBindRenderbuffer（GL_RENDERBUFFER，colorBuffer）; 

 glRenderbufferStorage（GL_RENDERBUFFER，GL_RGBA，width，height）; 

 glBindRenderbuffer（GL_RENDERBUFFER，0）; 

 //将渲染缓冲区作为颜色缓冲区附加到fbo 

 glFramebufferRenderbuffer（GL_FRAMEBUFFER，GL_COLOR_ATTACHMENT0，GL_RENDERBUFFER，colorBuffer）; 

有了扩展就可以用glRenderbufferStorageMultisample 作为ogles上msaa stay in tile 的解决方案（memoryless）

kGL_EXT_multisampled_render_to_texture

kGL_IMG_multisampled_render_to_texture

kGL_APPLE_framebuffer_multisample（apple现在用metal 

kGL_NV_framebuffer_multisample kGL_NV_framebuffer_blit
