Depth Color Sync doesn't seem to have an effect

Hi,

I am trying to calibrate color and depth streams so I can use depth thresholding on the color data.  When I call `device_->setDepthColorSyncEnabled(true)` It doesn't seem to effect the depth or color streams.  Is there something else I need to do to map the color to the depth? Or is this function not completed yet?

Thank you,
Jason
