PAD::TransformShapeWithClearanceToPolygon(): better polygonal shapes: 

- Oval and round pads ensure at least 16 segments per CIRCLE (like other shapes)
- For ERROR_OUTSIDE option, ensure the aarc approx error is the actual error,
not max allowed error.
These changes can be seen only for a large max allowed approx error, especially
when filling zones.
