Toggling the backlight is what my app wants to do only part of the
time. The rest of the time it wants to turn the backlight on, or turn
it off. A toggle command would work if I could determine the backlight
state.
There really should be an "official" way to at least detect the
backlight state; an official way to explicitly turn it on/off would be
icing on the cake. I have an app that needs it; I know there are others
out there, too. Please don't make us use unsupported and likely-to-
break-in-the-future methods.
