This function extends a polygon by a specified range. It also generates internal polygons caused by intersections.

The resulting polygon does not preserve the original shape of the input polygon (see screenshot above), but represents the range specified from the input polygon.

Example of usage is given in the m-file header (or type "help extendPoly").

Credit to NS for the self intersection algorithm.

v1.5 Replaced selfintersection algorithm because it yielded inaccurate results; added user definable resolution parameter for drawing the circle pieces of the resulting polygon.

v1.5: Replaced selfintersection algorithm because it yielded inaccurate results; added user definable resolution parameter for drawing the circle pieces of the resulting polygon.
1.3.0.0

New and faster CW/CCW detection method for the input polygon. Old method returned incorrect results when the polygon points have negative x-values only.
1.2.0.0

Added a bunch error and warning messages for badly formed input. Automatically closes input polygon if not closed (warning generated).
1.1.0.0

Fixed bug in determining if input polygon is defined CW or CCW
