I haven't examined current hardware, but my intent for Render (at some point) is to add a "gamma corrected" rendering mode where values are converted to "luminosity" before being added together, and then converted back to values. This conversion would use tables with the same content as the ICCCM XDCCC table, essentially an arbitrary array for each primary. >From your description, this should provide the ability to use luminosity, voltage or optical density, depending on what the application desired. (I intend that the conversion be associated with the Picture, allowing rather fine grained control).
