  // EGLNoConfigContectTest.cpp:
  //   EGL extension EGL_KHR_no_config_context allows a context to be created
  //   without a config specified. This means all surfaces are compatible.
  //   As a result compatibility checks are circumvented.
  //   This test suite creates and verifies creating a configless context
  //   and then verifies simple rendering to ensure compatibility.
