This adds an option to control at what time relative to the current frame the shutter is fully opened. Supported options are: - Shutter is starting to open at the current frame - Shutter is fully opened at the current frame - Shutter is fully closed at the current frame Custom shutter time offset is possible, same as custom curve for shutter openness but those are considered nice things to have rather than something crucial.
