Update padFootprint function

[Nisarg236]

Previously this function was scaling the footprint with respect to the coordinate frame 0,0 which could result in distortion. Also when the centroid is having large offset with 0,0 then it will just displace the footprint instead of padding.

Now it scales with respect to the centroid of the footprint.

another case (10,10), (10,12), (12,12) , (12,10)

another case (0,0), (0,2), (2,2), (2,0)

I have also tested the behaviour with negative values of padding (shrinking the footprint)

The 1st example looks suspicious: doesn't look like padded 10 cm but 2 or 3 🤔

This looks similar to this commit
Do both provide the same result? If so, this is simpler

Keep the formatting of the files you modify. i.e. never mix stiles

Hi you are right it wasnt 0.1 meters because it was scaling by percentage, I changed it to scale by meters and updated the image.
and now the functionality is the same as the one you shared.

So the outcome is now the same as with this commit?
Then better to use the commit,,, as the logic is much simpler 🤔

@corot I think you are missing the part he calculates the centroid of the polygon.
