Animated screen! (unfinished, now only draws, no animation code yet).
Fun though to see it all work. :)

NOTE: Mac ghost has timer bug, the GHOST_ProcessEvents() doesnt wake
up for timers.

NOTE2: Added while loop in wm_window_process_events() to force Ghost
giving all events to Blender. Timers otherwise don't accumulate...
might be needed to fix in ghost too.

I tend to think to code own timer, this ghost stuff is totally different
per platform.
