There are ARB extensions released every year (or more often, not
sure)... we don't track all ARB extensions. 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...

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).
