Ok, this is so minor.
But when comments of a function appears as hyperlink.
The comments which produce this result is:
/** Divide a polygon by a line, to 2 polygons.
\param polygon A number of points forming the polygon, counterclockwise. There is an edge from
last point to first point. Possible holes are clockwise.
\param l The line with equation \f$ a\cdot x+b\cdot y+c=0\f$ where \c l is the \c a, \c b, \c c
parameters.
\return An array of two polygons. First polygon is in negative semi-plane and second polygon is
in positive. Any of them (or both of them if \c polygon is ill-defined) can be empty. */
