20The SGI OpenGL conformance tests verify correct operation of OpenGL
21implementations.  I, Brian Paul, have been given a copy of the tests
22for testing Mesa.  The tests are not publicly available.
23</p>
24<p>
25This file has the latest results of testing Mesa with the OpenGL 1.2
26conformance tests.  Testing with the preliminary OpenGL 1.3 tests has
27also been done.  Mesa passes all the 1.3 tests.
28</p>
29<p>
30The tests were run using the software X11 device driver on 24-bpp
31and 16-bpp displays.
32</p>
33<p>
34Mesa 4.0 and later pass all conformance tests at all path levels.
35Note that this says nothing about the conformance of hardware drivers
36based upon Mesa.
