KLTUpdateTCBorder() is a convenience function that automatically recomputes 
and updates the <code>borderx</code> and <code>bordery</code> fields of the 
tracking context, so that the user doesn't have to ever touch these fields.
Unless the user desires direct control over the border,
this function should be called whenever
<code>smooth_sigma_fact</code>,
<code>pyramid_sigma_fact</code>, <code>window_width</code>,
<code>window_height</code>, or
<code>subsampling</code> is changed.
