Thanks a lot, I tried this, and it's forced me to provide  rendernode
option like this:
```
-display egl-headless,rendernode=/dev/dri/renderD128
```
My question is what I need to do to remove the need of rendernode, because
I wanna getting egl-headless to be usable on Windows.

Well, ui/egl-*.c needs some platform code to initialize egl on windows.
