That's really useful in itself, but no, I mean something that lets you read the actual OpenGl spec with the extension text patched in.
If you skim the text of an extension [1], you'll see an awful lot of this:
> Add a new section "Buffer Objects" between sections 2.8 and 2.9:
It'd be very nice to read those sections without having to have the full spec open in another window. Especially because some other extension you're using might be modifying the text as well.
