Run the following code with   Final_Frame=25  .

Watch the debug codes that come out.  The variable lshinx will come up
with a value that is not even in the range of the spline!!

#version unofficial MegaPov 0.4;
#include "colors.inc"
camera{
        location <10,5,-55>
        look_at <10,5,0>
        angle 45
        }
background {Gray35}
plane {y,-16       pigment {ForestGreen}      }
light_source {<12, 3, -51.8056> color White}

#init_spline {"Lshinx",

}

#declare Cmultclock=clock*2;
