+ * \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.
