//
// If a renderbuffer object is attached to one or more attachment points in the currently bound framebuffer, then it as if glFramebufferRenderbuffer had been called, with a renderbuffer of zero for each attachment point to which this image was attached in the currently bound framebuffer. In other words, this renderbuffer object is first detached from all attachment ponits in the currently bound framebuffer. ***Note that the renderbuffer image is specifically not detached from any non-bound framebuffers***
