Output session fading fixed for OSC and animation.

Browse Source 
Linear interpolation (instead of dichotomy converge) for fading at Session update. Mixing View update reads value of session fading to animate the cursor (which was preventing other manipulation of fading). Cleanup fading in OSC controller, with animation options and fade-in and fade-out controls.
