[Mesa-dev] [PATCH 1/2] i965: Use true AA line distance on G45/Ironlake.

2017-04-26 Thread Kenneth Graunke
The original Broadwater and Crestline platforms computed antialiased line distances using "manhattan" distance, aka a + b = c. Eaglelake and Cantiga added "true" distance, aka a^2 + b^2 = c^2, which is obviously superior. The G45 documentation indicates that the old manhattan distance setting is
