    mesa: Disallow deprecated SNORM formats for renderbuffers

    The OpenGL 3.2 core profile spec says:

        "The following base internal formats from table 3.11 are
        color-renderable: RED, RG, RGB, and RGBA. The sized internal formats
        from table 3.12 that have a color-renderable base internal format
        are also color-renderable. No other formats, including compressed
        internal formats, are color-renderable."

    The OpenGL 3.2 compatibility profile spec says (only ALPHA is added):

        "The following base internal formats from table 3.16 are
        color-renderable: ALPHA, RED, RG, RGB, and RGBA. The sized internal formats
        from table 3.17 that have a color-renderable base internal format
        are also color-renderable. No other formats, including compressed
        internal formats, are color-renderable."
