 683 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
 684 US$10,000 to the Mesa project to support its continuing development.
 685 Mesa is a free implementation of the OpenGL 3D graphics library and id's
 686 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
 687
 688 The donation will go to Keith Whitwell, who has been optimizing Mesa to
 689 improve performance on 3d hardware.  Thanks to Keith's work, many
 690 applications using Mesa 3.1 will see a dramatic performance increase
 691 over Mesa 3.0.  The donation will allow Keith to continue working on
 692 Mesa full time for some time to come.
