static void update_framebuffer_size ( struct gl_framebuffer *  fb ) [static] Examine all the framebuffer's renderbuffers to update the Width/Height fields of the framebuffer. If we have renderbuffers with different sizes, set the framebuffer's width and height to zero. Note: this is only intended for user-created framebuffers, not window-system framebuffes.
