0001-Use-egl-GetPlatformDisplayEXT-if-available.patch

eglGetDisplay forces the implementation to guess what kind of display pointer
it's been handled. Different libEGL will do different things, and in particular
glvnd does something different than Mesa.

eglGetPlatformDisplayEXT lets us be explicit about the display type. Mesa has
implemented this for over two years now (starting in 10.2).
