## @deftypefn {Function File} circles2d ()
## Description of functions operating on circles
##
## Circles are represented by their center and their radius:
## C = [xc yc r];
## One sometimes considers orientation of circle, by adding an extra
## boolean value in 4-th position, with value TRUE for direct (i.e.
## turning Counter-clockwise) circles.
##
## Circle arcs are represented by their center, their radius, the starting
## angle and the angle extent, both in degrees:
## CA = [xc yc r theta0 dtheta];
##
## Ellipses are represented by their center, their 2 semi-axis length, and
## their angle (in degrees) with Ox direction.
## E = [xc yc A B theta];
