This is needed to support the rare, but still legal scenario, when glDrawElemets is used with some index array data is stored in VBO's while the actual attributes (vertices) data is in immediate mode. When in immediate mode, we need to process the incodes, in order to know which vertex data to send, which was impossible without the caching. This commit introduces a new class GLSharedGroup, which will hold all data that can be shared by shared contexts (buffers are such data). This also makes the "Jet Cars Stunts" app work properly.
