Comment 14 for bug 1381625

Hey.

I'm researching the behaviour of backlight in the wild and my current theory is that brightness of zero can equally well mean "dim" or "totally off". I don't have a test for that yet so the sample range is very small (the hardware I have at home + several contributions from the community) but that seems to be the case.

I also looked at windows API and I'm about to look at the current Microsoft certification requirements. The API says that the values are arbitrary and no mapping to actual light intensity can be assumed.
