Apply the hue, value, saturation, and gamma values from the renderengine to screenspace renderables. Change the screenspace's own gamma value into an offset (#3293)

* Apply the hue, value, saturation, and gamma values from the renderengine to screenspace renderables.  Change the screenspace's own gamma value into an offset

* Make it clearer that the gamma correction is now an offset
