Arguments: point-x point-y circle-center-x circle-center-y radius
Returns as multiple value the coordinates of the point on the edge of
a circle where it is crossed by a line that passes through the center
of the circle and through an arbitrary
point. Returns nil
if the circle center and
the arbitrary point are the same.
The first two arguments are real numbers for the X and Y coordinates
of the arbitrary point. The third and fourth arguments are real
numbers for the coordinates of the center of the circle, and the last
argument is a real number for the radius of the circle. Returns two
real numbers for the X and Y coordinates of the intersection point, or
nil
.
