  28  * Simple regression test for bug #3050.  Create a texture and make a few
  29  * calls to \c glGetTexLevelParameteriv.  If the bug still exists, trying
  30  * to get \c GL_TEXTURE_WITDH will cause a protocol error.
  31  *
  32  * This test \b only applies to indirect-rendering.  This may mean that the
  33  * test needs to be run with the environment variable \c LIBGL_ALWAYS_INDIRECT
  34  * set to a non-zero value.
