Pseudo class for features in inactive layer

[derickson.e@…]

It would be helpful to have an :inactive pseudo-class available for paint styles, so that when working with the draw.data.inactive_color=false option, data in an inactive layer could be styled differently than data in an active layer, yet not the uniform gray that results when the draw.data.inactive_color option is set to true. For example, I would like to add to my paint style that the colors of highways in an inactive layer are darker shades or less saturated than the colors for highways in the active layer.

Thank you.
