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