[Mesa-dev] [PATCH] i965/aa: fixing anti-aliasing bug for thinnest width lines - GEN6

On SNB and IVB hw, for 1 pixel line thickness or less, the general anti-aliasing algorithm give up - garbage line is generated. Setting a Line Width of 0.0 specifies the rasterization of the “thinnest” (one-pixel-wide), non-antialiased lines. Lines rendered with zero Line Width are rasterized usi
