Description
See summary. The documentation says that if either the source or target buffer is NULL, that "the default framebuffer will be used". However this is not the case; instead, FBO 0 is used. This makes it impossible to use these functions with a QOpenGLWidget, as the widget's QOpenGLFramebufferObject is not available to the user, and there is no way to tell QOpenGLFramebufferObject::blitFramebuffer to use a buffer identified only by its handle.
