733<pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
734US$10,000 to the Mesa project to support its continuing development.
735Mesa is a free implementation of the OpenGL 3D graphics library and id's
736newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
737
738The donation will go to Keith Whitwell, who has been optimizing Mesa to
739improve performance on 3d hardware. Thanks to Keith's work, many
740applications using Mesa 3.1 will see a dramatic performance increase
741over Mesa 3.0. The donation will allow Keith to continue working on
742Mesa full time for some time to come.
