PlayIt broadcasts various wimp messages when certain events occur to enable any interested wimp tasks to respond acoordingly. This supersedes the old, potentially problematic, pollword mechanism.

Messages are only broadcast from PlayIt 1.59 onwards. All messages are broadcast and should not be claimed as they are informational only.

Nearly all messages include updated data pertaining to the event that caused the message which may greatly reduce the requirement to subsequently fetch the new state with a SWI.
