I'm glad that the topic of EGL platforming was split off, its a different question than the one I was raising in the "What is a MirRenderSurface?"
So really the question here is "should Mir have its own EGL_KHR_platform_mir". I'm not opposed to this in general. This goes back to the charter that we were given at the start of Mir, which is to accept drivers as they come to us, especially if they come to use in binary form with no intention from the driver authors to change anything about their drivers. The notable example of this is the Android platform, but the wider intention is to stay flexible for closed-source binary drivers that have been coming our way. So if we re-examine that question and decide that we're our own platform, then we can bolt other technologies on top via the use of shims and such. It is a bit more work for 'non-mir' platforms, especially when we have to deal with hybris and creating shim libraries and such to wrangle things into a mir-platform-interface (which at this point we don't define). I'd rather just continue saying that Mir is a WindowManager that can take plugins to different platforms, as opposed to saying Mir is a WindowManager and NativeWindowType, and non-mir platforms have to be adapted to the mir platform. It also is 'staying the course' as far as the story that we've been promulgating to driver developers. IMHO, The decision to define our own windowing type is something that will affect more than just the mir team (it has to do a bit with strategy), so would be good to get input from a wider audience.
