From 952e5d584f5aabe41298c278065fe628f3f7aa7a Mon Sep 17 00:00:00 2001
From: Gerd Hoffmann <kraxel@redhat.com>

Subject: [PATCH] egl-headless: add egl_create_context
We must set the correct context (via eglMakeCurrent) before
calling qemu_egl_create_context, so we need a thin wrapper and can't
hook qemu_egl_create_context directly as ->dpy_gl_ctx_create callback.
