   1 Conformance Testing
   2 ===================
   3
   4 The SGI OpenGL conformance tests verify correct operation of OpenGL
   5 implementations. I, Brian Paul, have been given a copy of the tests for
   6 testing Mesa. The tests are not publicly available.
   7
   8 This file has the latest results of testing Mesa with the OpenGL 1.2
   9 conformance tests. Testing with the preliminary OpenGL 1.3 tests has
  10 also been done. Mesa passes all the 1.3 tests.
  11
  12 The tests were run using the software X11 device driver on 24-bpp and
  13 16-bpp displays.
  14
  15 Mesa 4.0 and later pass all conformance tests at all path levels. Note
  16 that this says nothing about the conformance of hardware drivers based
  17 upon Mesa.
