From: Lyude Paul <ly...@redhat.com> This takes all of the gbm related code in wayland-glamor.c and moves it into it's own EGL backend for Xwayland, xwayland-glamor-gbm.c. Additionally, we add the egl_backend struct into xwl_screen in order to provide hooks for alternative EGL backends such as nvidia's EGLStreams.
