Currently the function to sort the vertices of the polygon (orderedpolygoncorners in lib/polygon.c) only works on convex polygons. Because it was originally designed for ImageWarp where we won't be dealing with concave polygons.

Write a function that is able to sort the polygon edges correctly even if the polygon is concave and use that function for the polygon mode of ImageCrop.
