Exposure Control - IPR Update

[a_nak]

Preface with i know that Auto Exposure and Auto WB are new features. However, It would be nice if the VFB would update when changes are made to Physical Camera Exposure Controls under the Environment and Effects panel. It works in Physical Camera settings, but not when adjusting the EV value in the Env and Effects panel.

Also, it would be even better if EV and other exposure controls did restart compute on renders in either IPR or GPU renders.
