Why did you make this a component?

[Peng, 2016/05/25 19:42:55]

Becatse GpuServiceMus has a global variable g_gpu_service, to avoid duplicate
copy in one executable image, we have to make this a shared library.

  public:
   explicit ContextProvider(mojo::ScopedMessagePipeHandle command_buffer_handle);
