This is important for benchmarking, or else all results will be bound to 60 FPS.

message:
  Activate sending a "swapinterval" signal over IPC. Add client api for software clients to request different swapintervals. (eglSwapInterval is not glued together just yet)
  Currently only swapinterval of 0 or 1 is supported. Fixes: https://bugs.launchpad.net/bugs/1130553.
