Why are these so special vs e.g. the ones released along with GL 4.5 but that weren't included in the spec? Or any of the other ones...Well. They're not really special I guess. This just follows from the discussion that went down on irc between me, glennk, fredrikh, ++.Should GL3.txt just become extension-implementation-status.txt and list all non-vendor-specific extensions? So far it has stuck to actual GL versions (and more recently GLES).We can keep it GL / GLES versions only. Or we can extend it to a extension-implementation-status.txt thing. Or we can split it into two different files. I really don't care to much either way. If we end up adding these extensions to the file then a rename and adding other ARB's is probably the way to go. There are positive and negative sides to both approaches, and its not my call to decide how, and if, we want this. It gives a nice overview but at the same time it has PR- and "needs-to-be-kept-updated"- implications that we may not want. I'm all ears for suggestions. -ThomasI like the idea of adding an "ARB Extensions" section and listing all the ARB extensions that aren't part of a particular GL version - simply in addition to the existing content, rather than reorganizing it. GL3.txt has been a misnomer for a while, but I don't care whether we rename it or not; it doesn't bother me. --KenI've assembled a list of extensions I *think* are not demanded by any current openGL specs, but I may have missed some. (I find it weird that I VAO's in any of the specs, for example) I could add all of them to a separate section to track them, or I can leave it as is and drop this patch. Up to you guys. 2.

GL_ARB_matrix_paletteIlia sent a list of extensions that are required for 2.1 and 3.0. There are a bunch of additional extensions, like the two above and GL_ARB_compatibility below that should be listed in GL3.txt. We never want these extensions ever. If we add them to that file, someone will do a bunch of work and submit a bunch of patches.
Maybe at the end of the doc there could be a list of extensions that Mesa will never implement? (potentially with short description why: "obsolete", "nobody uses", "bad idea" etc)
