AreaEllipse: add a ellipse to areainfo list for areafill.

SYNOPSIS

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)

FUNCTION

Add an ellipse to the vector buffer. It will be draw when AreaEnd() is called.

INPUTS

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)
