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.
