/**
 * \file bug_3050.c
 *
 * 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.
