InitArea -- Initialize vector collection matrix
InitArea( areainfo, buffer, maxvectors )

void InitArea(struct AreaInfo *, void *, SHORT);
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.
areainfo - pointer to AreaInfo structure
buffer - pointer to chunk of memory to collect vertices
maxvectors - max number of vectors this buffer can hold
Pointers are set up to begin storage of vectors done by
AreaMove, AreaDraw, and AreaEllipse.
