  59 <p>
  60 Mesa's directory tree has been overhauled.
  61 Things are better organized now with some thought toward future needs.
  62 </p>
  63 <p>
  64 In CVS, the latest Mesa 5.1 development code is now rooted under the
  65 <b>Mesa-newtree/</b> directory.  The old top-level <b>Mesa/</b> directory
  66 holds the Mesa 5.0.x code which will be abandoned at some point.

 626 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
 627 US$10,000 to the Mesa project to support its continuing development.
 628 Mesa is a free implementation of the OpenGL 3D graphics library and id's
 629 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
 630
 631 The donation will go to Keith Whitwell, who has been optimizing Mesa to
 632 improve performance on 3d hardware.  Thanks to Keith's work, many
 633 applications using Mesa 3.1 will see a dramatic performance increase
 634 over Mesa 3.0.  The donation will allow Keith to continue working on
 635 Mesa full time for some time to come.
