Bug Description

$ bin/mir_demo_server
$ bin/mir_demo_server --no-file --host $XDRUNTIME_DIR/mir_socket --test-client bin/mir_demo_client_eglplasma

expect: nested session shows plasma demo
actual: Can't eglInitialize

(This works fine with Mir 0.26.2, but fails with lp:mir)

May also have a problem with Mir-on-KMS (same scenario):

[2017-06-09 12:37:26.000134] <DEBUG> eglstream: EGLStream platform is unsupported: Missing required extensions: EGL_EXT_platform_device EGL_EXT_device_base

This looks like a potential problem:

std::vector<mir::ExtensionDescription> mgn::NestedDisplayPlatform::extensions() const
{
    return {}; // TODO can we support extensions transitively?
}
