1075 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1076 improve performance on 3d hardware.  Thanks to Keith's work, many
1077 applications using Mesa 3.1 will see a dramatic performance increase
1078 over Mesa 3.0.  The donation will allow Keith to continue working on
1079 Mesa full time for some time to come.
