from + guess :
get_angle(from, width, step, guess + step);
where from is the starting angle, width is the width of the letter,
and step controls
how small the steps along the ellipse are; smaller steps = greater accuracy
but more time. guess is mainly used to step along the function, but you can
start with an initial estimate if there's a reason to.
