#1 A node property to enable clicking through of overlays

[James C. Wilson]

A node property, which when "true" would enable the player to click through an overlaying node that is more then 0.5 opaque, to a hotspot on the background node, or to drag-pan on the background node. Example:
clickThough = true

This would be useful for simple flashlight effects, scratched telescope lenses, and thematic effects, like film grain and scratches.
