mesa/vbo: Treat attribute 0 and vertex as the same
This is supported by the pseudo-code on pages 27 and 28 (pages 41 and 42 of the PDF) of the OpenGL 2.1 spec. The last part of the implementation of ArrayElement is: if (generic attribute array 0 enabled) { if (generic vertex attribute 0 array normalization flag is set, and type is not FLOAT or DOUBLE) VertexAttrib[size]N[type]v(0, generic vertex attribute 0 array element i); else VertexAttrib[size][type]v(0, generic vertex attribute 0 array element i); } else if (vertex array enabled) { Vertex[size][type]v(vertex array element i); } Page 23 (page 37 of the PDF) of the same spec says: "Setting generic vertex attribute zero specifies a vertex; the four vertex coordinates are taken from the values of attribute zero. A Vertex2, Vertex3, or Vertex4 command is completely equivalent to the corresponding VertexAttrib* command with an index of zero." Fixes piglit test attribute0. NOTE: This is a candidate for stable branches. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Brian Paul <[email protected]>
