Subject: * This doesn't fix mantis 3522, but it should mitigate it. * If the
 start position is outside of the region on the X and Y, put the user in the
 center of the region and then damp the Z position at 720 if necessary.  If
 the start position is not outside of the region on the X or Y, then don't
 check the Z.
