-The compositor maintains a content update count for each registered 
-surface that determines when content ready notifications will be 
-completed. The content update count is internally incremented by the 
-compositor every time it receives a valid content update for a 
-registered surface. Frames may be skipped if the client submits 
-content updates too fast, meaning that not every update is displayed 
-on screen. The first valid content update sets the content update 
-count to one. Updates sent before the surface is registered do not 
-affect the content update count. Content ready notifications for 
-aContentUpdate = 1 will only be successfully completed after at least
-one content update has been received.
