Mesa now matches nvidia's behavior.
If you feel that these cause significant headaches for game/app
developers feel free to throw in the stable tag on the series.
I only found this during the course of debugging an app that used
glPush/PopAttrib and I was trimming down the attrib mask. I hit 0 at
one point and discovered the error/bug then. I'm not aware of any apps
that hit this.
R-b?
