RFE: Extend the DPMS/FBPM API to include the following features:
- Events: An application should be able to listen to events generated by the
DPMS/FBPM extension which inform it about state changes (e.g. monitor is
turned-off by timeout, forced off by command, powering-up again by command or
input event etc. (same of FBPM))
- "suspend DPMS/FBPM": An application should be able to "suspend" the DPMS (and
FBPM) functiontionality via an API call until either a 2nd API call is made to
undo this or the client connection which created the "lock" is lost. This is
mainly usefull for stuff like video players which currently simply disable DPMS
during playback and restore it on stop/pause (the problem is that the DPMS
extension remains disabled when the client crashes and that running multiple
clients in parallel may end up in an unexpected DPMS status if you do not exit
the players in the reverse order how you started them... ;-/ ... an API in the
DPMS/FBPM extension would cure this mess...).
