    mesa: Use VERT_ATTRIB_* indexed array in gl_array_object.

    Replace the distinct struct gl_client_array members in gl_array_object by
    an array of gl_client_arrays indexed by VERT_ATTRIB_*.
    Renumber the vertex attributes slightly to keep the old semantics of the
    distinct array members. Make use of the upper 32 bits in VERT_BIT_*.
    Update all occurances of the distinct struct members with the array
    equivalents.

Comment 1 Mathias Fröhlich 2011-12-02 23:27:34 UTC 
Commit b14c06e10d570edcb4dcbea173d71751563616e7 fixes this on classic swrast.
Given the change, I guess that this also fixes this test on an intel chip. Can you verify?
Thanks!
