Message : Generate CONTEXT_LOST errors on every GL call. The robustness spec states that all GL calls should generate context lost errors when the context is lost. This behaviour was lost due to some context lookup optimizations but can be re-added at no cost by updating the autogenerated entry points. Updated the ContextLostTest to cover the repeated error generation behaviour.
