Code review comment for lp:~cemil-azizoglu/mir/use_egl_native_window

Alright, I think we've gotten to the bottom of this in the email chain.

We really need a shim EGL platform to adapt EGL_KHR_mir_platform to EGL_KHR_android_platform. This adaptation should be done in the shim, not within the android client platform.

I'd prefer a shim-layer to be proposed instead of this, just on the basis of it having 2-step initialization, deferred errors from ErrorDriverInterpreter and introducing temporary confusion about MirRenderSurface (which sparked all that email discussion)
