     10 <h1>Conformance</h1>
     11 
     12 <p>
     13 The SGI OpenGL conformance tests verify correct operation of OpenGL
     14 implementations.  I, Brian Paul, have been given a copy of the tests
     15 for testing Mesa.  The tests are not publically available.
     16 </p>
     17 <p>
     18 This file has the latest results of testing Mesa with the OpenGL 1.2
     19 conformance tests.  Testing with the preliminary OpenGL 1.3 tests has
     20 also been done.  Mesa passes all the 1.3 tests.
     21 </p>
     22 <p>
     23 The tests were run using the software X11 device driver on 24-bpp
     24 and 16-bpp displays.
     25 </p>
     26 <p>
     27 Mesa 4.0 and later pass all conformance tests at all path levels.
     28 Note that this says nothing about the conformance of hardware drivers
     29 based upon Mesa.

     38 Test that all API functions accept the legal parameters and reject
     39 illegal parameters.  The result of each test is either pass or fail.
