I couldn't find this piece of text (though I would have hoped it
existed). Care to cite which spec in the comment?
3.1 spec, 3rd paragraph of page 199. Or
http://www.opengl.org/sdk/docs/man3/xhtml/glBlitFramebuffer.xml in the
errors section.
It's not in the 3.0 spec, but I'm sure that was an oversight.
Same story for the buffer datatype check I posted in a later patch.
