1036 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1037 US$10,000 to the Mesa project to support its continuing development.
1038 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1039 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1040
1041 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1042 improve performance on 3d hardware.  Thanks to Keith's work, many
1043 applications using Mesa 3.1 will see a dramatic performance increase
1044 over Mesa 3.0.  The donation will allow Keith to continue working on
1045 Mesa full time for some time to come.
