"glmark2-es2-wayland --fullscreen" fails to display

[AlanGriffiths]

If WAYLAND_DEBUG=client is set, then it is clear that buffers are being submitted, but there's no window (fullscreen or otherwise) shown.

Looks as though the problem is:

"The compositor must reply to this request with a configure event with the dimensions for the output on which the surface will be made fullscreen."

Which we don't honour as the window management "window" has not yet been created in Mir. Only when a buffer is submitted do we create the window (and size the surface).
