* The result is areas with a margin of m_ZoneMinThickness/2
* When drawing outline with segments having a thickness of m_ZoneMinThickness, the
* outlines will match exactly the initial outlines
* 3 - Add all non filled areas (pads, tracks) in group B with a clearance of m_Clearance +
* m_ZoneMinThickness/2
* in a buffer
* - If Thermal shapes are wanted, add non filled area, in order to create these thermal shapes
* 4 - calculates the polygon A - B
