867 US$10,000 to the Mesa project to support its continuing development.
868 Mesa is a free implementation of the OpenGL 3D graphics library and id's
869 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
870
871 The donation will go to Keith Whitwell, who has been optimizing Mesa to
872 improve performance on 3d hardware. Thanks to Keith's work, many
873 applications using Mesa 3.1 will see a dramatic performance increase
874 over Mesa 3.0. The donation will allow Keith to continue working on
875 Mesa full time for some time to come.
