Where are the Motion Blur controls in 2.76b as shown in the Manual? Under the Render tab (Cycles Render), the motion blur options are very simple compared to what I see in the Manual:  https://www.blender.org/manual/render/cycles/settings/motion_blur.html#options

Where can I find these extra motion blur controls?
Looks like they already updated the documentation for the the upcoming 2.77 release. The test builds do have these extended controls.
