AreaEllipse -- add a ellipse to areainfo list for areafill.
error = AreaEllipse( rp, cx, cy, a, b )
d0 a1 d0:16 d1:16 d2:16 d3:16
LONG AreaEllipse( struct RastPort *, SHORT, SHORT, SHORT, SHORT)
Add an ellipse to the vector buffer. It will be draw when AreaEnd() is
called.
rp - pointer to a RastPort structure
cx - x coordinate of the centerpoint relative to the rastport.
cy - y coordinate of the centerpoint relative to the rastport.
a - the horizontal radius of the ellipse (note: a must be > 0)
b - the vertical radius of the ellipse (note: b must be > 0)
error - zero for success, or -1 if there is no space left in the
vector list
