clip3d - Clips the polygon given in vtx using fixed point math. Allegro game programming library.

       Fixed point version of clip3d_f(). This function  should  be  used  with  caution,  due  to  the  limited
       precision of fixed point arithmetic and high chance of rounding errors: the floating point code is better
       for most situations.
