 *
 *  This class is an adaptor between the mp_alignEyesMex and the interpolator that does the image
 *  rotation. Primarily it does some setup, calls the interpolator, then does some teardown.
 *  Arguments:
 *    pixels: input image (full size)
 *    patchSize: size (width and height) for the rotated face image
 *    xl, xr, yl, yr: eye coordinates
 *  Return value:
 *    The rotated and cropped face. It was allocated with new, so needs to be deleted when the caller is done with it.

/** mp_threadedGabor runs multiple gabors in separate threads.
 * Each of three gabors runs in a separate thread on a different group of the kernels. Thread support is supplied by the Boost library.
 *
 * In some cases (quad processor G5) this seems to add as much as a %30 speed increase.
