38 * \brief RenderContext that can be used when no render context is present.
39 *
40 * Some patterns (e.g. a test class inheriting from glu::CallLogWrapper)
41 * currently depend on having access to the glw::Functions already in test
42 * case constructor; in such situations there may not be a proper render
43 * context available (like in test case list dumping mode). This is a
44 * simple workaround for that: a dummy render context with a glw::Functions
45 * containing just null pointers.
