Use a line to split a polygon into two parts.

;Usage:

:<code>pgsplit(<var>X</var>, <var>IX</var>, <var>PX1<sub>scalar</sub></var>, <var>PY1<sub>scalar</sub></var>), <var>PX2<sub>scalar</sub></var>, <var>PY2<sub>scalar</sub></var>)</code>

:;<var>X</var>:a [[../#polygons|closed point-list]] or a [[../#polygons|polygon-stream]] defining one or more polygons.

:;<var>IX</var>:The index of the polygon of ''X'' to be splitted; 0 <= <var>IX</var> < <code>[[../pgget|pgget]](''X'')</code>

:;<var>PX1, PY1, PX2, PY2</var>: The points <''PX1'',''PY1''> and <''PX2'',''PY2''> defining the line to split the polygon. There must be exactly two intersections of the line with the polygon!

;Result: The result ''r'' is a [[../#polygons|polygon-stream]] containing the two split parts of the polygon.
