As one of the people who complained: the big issue I had with the
surfaceless platform was that the only way to use it was to set an
environment variable before calling eglGetDisplay, which is just
pointlessly unlike how you use every other platform. I was _happy_ when
I discovered the feature, I was only unhappy with its interface.
