recognize other geometric shapes about aforge

[GoogleCodeExporter]

Could you please clarify what is this ticket about? Do you ask for detection of 
other shapes or do you suggest a way to detect ellipses? If you suggest, then I 
would say it does not look right to detect ellipses using circle detection 
routine with large distortion limit. Ellipse has well defined equation, which 
needs to be used to find how well is the points’ fit to the shape.

I know that ellipse has well defined equation, but the shapechecker does not 
recognize ellipses but only circle. I suggest a way to detect all type of 
shapes inserting also the ellipse equation, I use the method described in the 
issue because the shapechecker has only IsCircle method. Once it will detect 
also ellipses, you can use my suggestion to detect annulus, or annulus sectors 
with start angle, end angle and arcwidth which for circles is: (outer circle 
width - inner circle width) / 2, for ellipses i don't know
