Shouldn't these be updated in sync?
Out-of-tree drivers, such as the legacy DRI1 drivers, won't be updated in sync (or likely ever). I believe there are also at least two closed source drivers (though that isn't a good reason not to do this change). Ian might recall some other reasons. Leaving the functions there, but having them return INVALID_OPERATION (like generic_nop does) would likely route around this issue. Not sure whether deleting support for this extension is a good idea or not. I can't think of any applications that use it offhand, but I haven't really looked into it either...if the NVIDIA blob doesn't expose it, that's a good data point... --Ken
