  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.
