Re: [Mesa3d-dev] GL_SGI_texture_color_table bug?

...and thanks for the fix :)

Now I changed the transfer function to:

(line 196 in colortable_bug.c:)

/* init colortable */
for( i = 0; i < 256; i++ ) {
	transfer_func[i][0] = i;
	transfer_func[i][1] = 0;
	transfer_func[i][2] = 0;
	transfer_func[i][3] = 255;
}

and I believe the resulting image should be red.
The Onyx gives me that but Mesa stays grayscale.

I think the reason is that the one-dimensional texture
is expanded in 
swrast_texture_table_lookup (s_texture.c: line 4194),
but in texture_apply (s_texture.c: line 4225),
specifically (s_texture.c: line 3910)
only the red component is used.

Thanks for your opinion,

Andreas
