This desynchronizes our rendering loop with the vblank cycle. In case a compositor doesn't swap buffers but schedules a frame, emitting a frame event immediately enters a busy-loop. Instead, ask the backend to send a frame when appropriate. On Wayland we can just register a frame callback on our surface. On DRM we can do a no-op pageflip. Fixes #617 Fixes swaywm/sway#2748
