From what you say this won't be easy - you can't change the angles 
of 'corners' unless you are altering the coords of the points (if you want to 
preserve straight sides for your polygons, that is). And if ARE changing the 
coordinates of the points, can you decide which points are on correct 
locations and which ones are skewed ?
