Yes, the "intensity" wording is better in my opinion.

The Mustek backend had RGB lineart and halftone modes. I don't know any
Mustek scanner that can do this and so I removed these modes. The old code
looked like it would use 1 for max intensity and 0 for min intensity. Maybe
David Mosberger-Tang can tell about the idea of these modes.
