NAME   

        InitArea -- Initialize vector collection matrix

   SYNOPSIS

     InitArea( areainfo, buffer, maxvectors )
                    a0          a1      d0

        void InitArea(struct areainfo *, void *, short);

   FUNCTION
        This function provides initialization for the vector collection matrix
        such that it has a size of (max vectors ).  The size of the region
        pointed to by buffer (short pointer) should be five (5) times as large
        as maxvectors. This size is in bytes.  Areafills done by using areamove,
        areadraw, and areaend must have enough space allocated in this table to
        store all the points of the largest fill. areaellipse takes up two
        vectors for every call. If AreaMove/Draw/Ellipse detect too many
        vectors going into the buffer they will return -1.

   INPUTS
        areainfo - pointer to areainfo structure
        buffer - pointer to chunk of memory to collect vertices
        maxvectors - max number of vectors this buffer can hold

   RESULT
        Pointers are set up to begin storage of vectors done by
        areamove, areadraw, and areaellipse.
