Title: Real-valued sliders

I need a slider / scale that will take `Real` values for the range, so we can use them in the `ImageView` package to set the image contrast. Before I break anything, I'd like to get a few eyes on the changes.

The one part that's really not clear to me is how to handle `get_value()`, so for right now I've left it alone.
