 *  @todo This file contains two things that represent the same thing: a
 *        KinectInfo class and a kinectInfo_t struct. I would much prefer
 *        to use the class since this is the "proper C++ thing to do", but it
 *        turns out that for a variety of reasons unbeknownst to me at the
 *        time of this writing, it's a major pain in the ass to do so. It's
 *        a worthy goal to pursue a conversion to the class form, and most
 *        of the work should be done.
