Do you mean remove the various #ifdef XMIR bits, or *all* the bits 
gated on xorgMir? Some of that's not going to be trivial to hide away 
in a header.

I'm not sure what you mean here - Xmir exposes the on-buffer-available 
callback, which gets triggered when swap_buffers has returned the next 
buffer to render to. This is what I'd think of as the refresh 
heartbeat. Is this not what you mean?

If you're rendering as fast as possible, this will be a 
once-per-compositor-vblank event.
