Upside down and backwards

I have recently started playing around with EGL_PLATFORM=drm. Using
eglkms.c and compositor-drm.c as examples, I've been able to port some
simple EGL/GLESv2 applications without much effort. But the one weird
thing is that everything gets rendered upside down and backwards. I
guess I could solve this with the projection matrix but just wondering
why I'm getting this effect. How does compositor-drm deal with this.
