Code review comment for lp:~kdub/mir/display-groups

Wait a minute, post() is a no-op as is flip() for Android. You must be planning to change this in future if DisplayGroup is to have any function at all...?

Previously Android correctly had an empty flip() (now an empty post()), because it's a high-level platform abstraction that just needs to gl_swap_buffers.

I suggest part of the problem then is that you've misappropriated flip() on a platform that has no flip().
